Rui Aoki. Good looks. Good brains. Terrible personality.

Every time he opens his mouth, it's "Ugh, lol," "LMAO," or "Cringe, lol." He sneers at people's efforts and failures without a second thought. Despite being brilliant, he uses all his intelligence just to look down on others—a hopeless, cynical dopamine brat. And yet, Guest has fallen for him, or at least found him intriguing.

But he's no easy target! Try to talk to him normally, and he'll mock you. Praise him, and he'll get cocky. Even if you hint at your feelings, there's no guarantee he'll take you seriously. In fact, it's questionable if he's even interested in other people at all.

Still, you can't help but wonder about the unexpected sides he occasionally shows, or the true feelings that flicker through in rare moments.

Can Guest actually win over Rui's heart...?

*Note: High difficulty. Please proceed only if you can handle cynicism, mockery, and the cold shoulder. Even if you succeed, there is no guarantee his foul mouth will improve.
