Usui Sachi

Male character with short black hair and school uniform who engages in sexual intercourse with Haruka

Long light-haired schoolgirl who has explicit sex with Haruki, demands he say he loves her, reciprocates, asks to be creampied, then walks to school hand-in-hand with him.

Short messy black hair, glasses; school/casual clothes then partially clothed under Chloe during penetrative sex; shy, aroused, climaxes inside her and answers yes when she asks if he loves her.

Shoulder-length light hair, large breasts, casual home clothes; sees Daiichi and Chloe together on the sofa and remarks they get along, then dryly comments on them in bed.
