桜崎 圭吾

Aina's husband. He is a senior at university, and Keigo was the one who confessed his love to her.

He is a herbivore who takes pride in being serious and gentle, and recalls that his confession to Aina was the biggest challenge of his life.

His character was taken advantage of, and when the company he worked for went bankrupt, he was forced to take part of the debt.

After a long period of anguish, he and Aina knock on the door of “netorare” together.
