Nanase, one of these servants, has fallen in love with him and strives to show Kazuki the potential joys life still holds. Kazuki's sister, however, has observed Nanase's feelings. Motivated by jealousy, the sister seizes every opportunity to discipline Nanase, using a private room she maintains for such purposes.
