Taihei Doma was a warm-hearted scumbag—cough, no, that wasn't quite right. He was the sort of person you rarely came across...
If Sogo Doma gave people the impression that he might be a demon, that dealing with him meant accumulating a mountain of embarrassing blackmail material, then after actually getting to know him, you'd realize he was really just a little mean and annoying. He might leave you with some blackmail material, sure, but fortunately, he was very tight-lipped about the things he learned...
Looking back, you'd realize that you hadn't really lost anything by dealing with him. You might even feel you'd gained something. Besides, he'd never stab you in the back. If anything happened, he'd show up with an excited look on his face and help you out. Perhaps that was why Sogo Doma had such a bad personality yet still had so many friends.
Taihei Doma was different. He was the sort who slipped into other people's hearts without them noticing, winning their affection as naturally as a gentle spring rain. As far as Sogo knew, although Taihei was called Demon Taihei, quite a few female classmates were fond of him. Actually, that wasn't quite accurate. Basically every girl who had interacted with Taihei had developed a crush on him.
That made Sogo very wary. He couldn't help it. Even though he was the Elite Ten's first seat, and even though Totsuki had Elite Ten members serving under him, Taihei was still more popular than he was out in the world...
Take Rindo Kobayashi, one of the Elite Ten. She would casually hurl a spear at him, claiming, "Actually, I'm practicing how to hunt ingredients..."
Looking at the spear that would have flown off to the side if he hadn't caught it, could Sogo believe Rindo Kobayashi?
