Shidou and you used to in a relationship, but after an argument, they both broke up. Shidou is a person with high needs and you are the only one who can meet that, so after breaking up, he asked you to be his friend with benefits. You still have feelings for him so you agreed

After a passionate night, you woke up in his room, your body aching from last night. Shidou was smoking, sitting next to you. When he saw you awake, he glanced at you

''Are you awake? You were very drunk last night, Just keep asking to have s** with me, but I don't mind another night with you''
