The World seems Realistic but Why do I have a Leveling System?

"The number you have dialed is not responding..."

"Oh right, she was currently in that place."

Sheila was desperate in looking for a backup that her brain stopped working and forget that Ria was still in the Trial Tower. It seems that Ria spent a lot of time in there since by now, 6 hours should have passed in there. Sheila gets up from the chair before telling her mother that she will be in her room and headed upstairs. 

Click!

Once she steps into her room, she immediately locked the door. Since Sheila is going to visit Ria in the Trial Tower, she didn't want her mother to suddenly come into her room and finds out that she has gone. Before teleporting into the Trial Tower, Sheila used her detection skill to make sure that she was alone in her room, and no one else is here. 

Sheila was still wary of her surroundings due to past events. She didn't like the feeling of being someone's puppet while not knowing anything and just followed the script that was given. Although that previous event told her the systems not just listening but also watching her the whole time, she still has her suspicions that someone else, a living being like her is actually the one behind the system. 

The reason is that at the time when Ria told her it was from someone else, Sheila had used her skill to the maximum potential and she found a clue that shows someone did, in fact, come into her room. It wasn't her mother nor herself but someone unknown. The fact that the Presence Detection skill level up to 3 showed that she is not wrong. 

Or maybe, the clue was left behind for her? After all, if there's a person who managed the system, it should know how it works. Sheila was conflicted on whether or not to believe the clue that was left behind. Because she is not sure about it, she didn't tell Ria and kept it a secret for now. She didn't want Ria to be worried unnecessarily. 

The heat sign she feels from her skill only showed one downstairs in the kitchen, which means no one else is here except mother and herself. Sheila slowly opened her eyes after she turned off the detection skill before teleporting herself into the Trial Tower. 

"Hap!"

Sheila looked over when she heard the noise Ria made when she swung her silver sword. Ria was currently fighting against three slimes that have her surrounded. Although she was sweating, it doesn't seem that she would fail here. Whenever the slime hit her, she would retreat to heal herself before jumping back into the battle and resume her fights. 

It sounds easy when said but to do so is very hard. When Ria was retreating, she has to make sure that she didn't go to the wrong side. She also needs to heal faster since although the slime is slow, her healing also takes time. It wasn't just that, she also needs to be on her guard for any possible sneak attack while she was healing. 

And that was why she was surprised to see Sheila when she went back to heal herself while warily looking around her surroundings before the figure of Sheila appears in her view. Thankfully it didn't distract her from the battle as she resumes the fight to finish off the last slime. 

"What are you doing here?"

Ria asked Sheila while she was wiping the sweat on her forehead with the handkerchief she kept in the inventory. She had thought Sheila would be busy teaching the girl about the Trial Tower and stuff, that was why she didn't expect to see her here. 

"I have already finished my business with Sylvia and just get back home."

Sheila answered promptly, knowing that Ria would be asking her such a question. 

"Is that so, then are you here simply to watch me?"

"Well, that is.."

Sheila slowly said while scratching her head. 

"You know, umm.."

"Just get on it."

"My father is coming back home, so I need you to be my backup! Please!"

Sheila shouted, stating the reason behind her presence being here before proceeding to kneel in front of Ria. The second person that Sheila is scared of is her father; of course, the first place is her mother. But since she has been living with Sara a lot longer than her father, she has gotten used to Sara. 

Even up until now she never knew what kind of job her father worked for, and if asked, her father would dodge the question by saying it was a business but didn't describe anything else. Sara seems to know about it, but she also keeps her mouth shut. Sheila had long given up on asking about her father's actual 'business'.

"Really? Uncle is coming back home?"

"Yes, that's why I need you there if anything untoward happens."

"Well, knowing you, it's possible."

"But I have one condition."

"Umm, what is it?"

Sheila had thought that Ria would agree right away but didn't expect her to give a condition. That was why Sheila was nervous when she asked Ria. 

"It's nothing much, but you can buy skills or whatever is in the system shop, right?"

"Yes, what about it?"

"The one condition is I also want that disguise skill."

When Sheila had used the disguise skill in front of her, Ria was amazed by the scene. And she was even more awestruck when Sheila mentioned that she could potentially 'disguise' herself into an animal! There's actually one secret about Ria that Sheila didn't know about, and that is, she is in love with the fluffiness of a cat! 

Whenever Sheila shared cute videos about cats to Ria, she would always act like she didn't care but secretly watched it while squealing like an ordinary girl. She didn't tell Sheila about it is because she finds it embarrassing to do so. Yes, the reason she wants a disguise skill book is that she simply wonders how it feels to become like the ball of fluff that she used to appreciate and admire at all time. 

"Why would you want it? I don't think you have any use of it."

"Don't ask any questions! If you want me there, you must follow that one simple condition, or I won't help you."

Seeing Ria being persistent and didn't want to explain further, Sheila could only shake her head and agreed to it. Because Sheila had learned the skill, the cost for the skill book in the shop is cheaper than the actual price. She didn't expect to learn something new when she was going to buy the skill book. 

Once Sheila had bought it with the gold she had saved up, she went ahead and transferred it to Ria's inventory. To Ria, Sheila was just staring in front of her(she couldn't see the screen of system shop) for a moment before Sheila told her that it has already been transferred to her inventory. 

Ria pulled out the card out of the pocket in anticipation before proceeding to check the inventory. Aside from all the consumable food and drink, she saw a new item in the inventory slot, which showed the icon as a small book. In her excitement, Ria immediately summons the skill book out of the inventory before placing her hands onto it. But the next thing happen was out of her expectation.

『 You can't learn this skill due to the difference in class! 』

A new window surfaced in front of her view while she was holding onto the skill book in her hands. 

"No..no way..."

Ria crumbles down and falls on her knees in despair. Her hopes and dreams have been destroyed ruthlessly without any restraint! She couldn't believe it! Not giving up, Ria let go of the book before placing her hands onto it once again, but the same window appears, notifying her that it is not possible no matter how she does it. 

Looking at the crestfallen Ria, Sheila didn't know what to say. To be honest, she also didn't expect such a thing to happen. If she had known, she wouldn't have bought it in the first place. It would just be a waste of gold, after all! 

Sheila picked up the skill book that was thrown away by Ria to the side before storing it back into her inventory. Since she had already learned it, she could freely touch it without any issue. Maybe she could give it to Sylvia? Her class is an assassin, so it should be suitable for the disguise skill book isn't? While having such thoughts, Sheila went over to Ria before giving a pat onto the latter's back.

"Uhm, cheer up? I didn't expect to see a class restriction since I don't have any class and thought you could learn the skill too."

"...just kill me."

Ria slowly muttered with the eyes that have lost its shine; it was the same eyes of a dead fish. She feels like the world that she believed was once beautiful has become very dull now. Sheila stood there awkwardly and didn't know what to do, but after a few seconds passed, she went over and wrapped her arms around Ria. She thought that maybe by doing this, the crestfallen Ria would cheer up when she feels the warmth from being in contact with her body. 

As to how she comes to such thought, it was because she had a feeling when she was sad, Ria would always give her a tight hug. The warm feeling from Ria's body makes her feel like she was slowly healed. Maybe the hug works, or perhaps Ria had come back to her senses as she pulled the hug apart and told Sheila that she would come to her place once she left the Trial Tower. 

"Once I had enough gold, I would definitely buy you something good from the shop!"

"It's fine; I don't need it."

Sheila promised to herself that once she had enough gold, she would buy one skill that Ria could use. Actually, she had enough gold to buy one skill book from one of the four basic elements. But Sheila thought that the healer Ria couldn't use other elements aside from the light, which is the healing magic from her class. That was why Sheila didn't get it for Ria; she would rather save up the gold and buy her a more powerful weapon instead. 

Maybe she could get a good staff for Ria that has useful abilities such as shortening the spell casting time or buffing her healing magic, something like godly staff in the novels. Sheila had gone through the system's shop when she was browsing on the weapon corner and noticed plentiful godly weapons there. But the price is, of course, mind-blowing.
