However, due to family reasons, Hinako has to play the role of the โperfect young ladyโ at school. Wanting to protect her, Itsuki takes care of her in a very caring manner. Eventually, Hinako begins to fawn on Itsuki with all her mightโฆ โNowโฆif Itsuki isn’t around, I would hate it.โ This is a love story that begins with a cute young lady with a gap that transcends the master-servant relationship.
