While looking for a job in Tokyo, Yui-chan, who is extremely cute among her cousins, decided to rent out our vacant room. Yui, who has become a sexy woman who doesn't seem like she's younger, always glimpses defenselessly... I'm worried about whether I'm not seeing me as a man or whether I'm seducing him... I'm continuing to worry about this and wonder if I'm tempting him... I'm on the verge of explosion!
