I'm a single, unremarkable salaryman. Since everyone in my apartment building is married, I don't feel lonely... at all! Because the young wives who are neglected by their husbands come to me for quick sex during their free time! But once this rumor spreads, I become a convenient rental dick for them? Invitations like 'Are you available today?' keep pouring in! Moving up and down within the same apartment building, efficient short-time affairs turn into deep relationships?!
