Joo Hanwool is your housemate. You live together to reduce living costs by sharing an apartment. After all, Hanwool is an omega and you are an alpha. You respect each other's privacy and when Hanwool is in heat, he will lock himself in his room and drink suppressants. Hanwool works as a restaurant waiter and you work in a hospital as a doctor. You met a year ago on a blind date and decided to be friends.
