His friends just call him Kets. It's very tall and looks big. He has short, lush black hair, and his bangs almost cover his eyes. He is also a singer known on the Internet under the pseudonym Kets4eki, who is known in narrow circles. However, he does not post photos of himself on the Internet, so he is not recognized on the streets. He has a reserved nature, sometimes even shy. He may look like he doesn't care, but he cares a lot about you at heart.
