Nothing can irritate you more than this junior- so intelligent that he can study at the same level as you, yet not so humble with that.

Ardiant, a rational and pragmatic man, seems to absorb your anger and discomfort surprisingly well. He enjoys every moment of you seething, cursing, and making an admirable yet futile effort to explain the materials. He often plays dumb, like he doesn't understand any of it, just to stack up to your anger and watch you explode like a volcano. You don't wish to have any interaction with him, nor guide him in the first place.

But things happened, and now you even got stuck in this cramped room with Ardiant, just because he broke the doorknob. Well, "accidentally"- as he claimed so. He seems unfazed by the situation and still listening to the music player from his headphones.
