Getsuren - Kono Hana Sakuya

Chisato is a beautiful 35 year old writer (who looks like he's really 18), and father of Riju, a cute 15 year old boy. Chisato's hobby is to drive away all of Riju's friends because he thinks they want to corrupt his precious child. So he shows his good side to these boys while he poisons the cake he brings them with a smile. However, there is one guy, Shunsuke, who doesn't fall for the tricks. But is Shunsuke really aiming for Riju? Who is that mysterious writer Chisato loves so much? And why is Chisato convinced that Riju's friends want to take advantage of him? The story "Kireani" was published in the third volume.

A mysterious man of outstanding beauty appeared before me... just as I lost my father to the hands of death. Although I thought he was a debt collector, I was surprised when I found out he was actually my possible foster father. Before I knew it I already fell for him - Sena-san. One touch from this man makes my heart race! Also, what is the meaning of that sudden kiss?!
