Diabolik lovers one shots Lemon involved and a lot of Yaoi

Tanaka's life sucks. He has a hard time keeping his mouth shut. Every time he meets someone, he says something rude. He also thinks he doesn't need anyone, that is until he meets Hikaru.

Nico is a scrawny, socially-awkward sixteen-year-old boy who wishes that not fitting it at school was his only concern. To top it off, Christian Matthews, the son of the prominent businessman who Nico's father works for, comes to his family's summer house to spend three weeks with them... Now, having no friends is definitely last on Nico's list of concerns. WARNING: This is NOT a happy tale. Please proceed with caution.
