Kazunari Kyogoku

His name Kazunari is spelled with the character for "one" and the character for "become". A traumatized, former thug who can hear people's inner voices. He made it all the way up to company owner. He always smartly calculates his profits and losses, and prioritizes what's best for himself. However, he's a “good person” deep inside, so he somehow ends up caring for people. In the end, he's not seen as cool and smart, but rather as a “good guy who's simply a tsundere”. He can't understand why. Easily moved by affection. Bad sleeping posture. Dislikes carrots. If only he were a little more honest, then he would have an easier life.
