Kazuo Kinoshita

Kazuya's father. 55 years old. Currently manages "Kazu Liquor Store" in place of Kazu. He is often caught up in Kazu's unreasonable demands, but unlike Harumi who goes along with everything, he has tried to stop him several times. He witnesses Kazuya giving money to Mizuhara and misunderstands that Kazuya is in debt to Mizuhara, later pressing him to break up if it's a half-hearted relationship.
