Chichi Chichi

One day, a picture book writer named Yorozu Hiraku was asked by his close online friend, Chintarou, if they could share a room together while he attended a nearby university. Although they only knew each other through online interactions, Hikaru agrees to it without much thought. However unbeknownst to Hikaru, Chintarou, despite having a male name, is actually a girl... a very well endowed girl.
