'We are bound to each other by a contract.' Though Teyvat has yet to be but Mondstadht and Liyue, the world is vast. However, what happens to the rest of the world doesn't concern Childe. In his mind, he only cares for battles, wars, and blood. Perhaps the motivation is to protect his family, or, perhaps, the motive is revenge on the creature that lays in the abyss, waiting to strike at any moment. Or perhaps, he wishes to accomplish both and understand the contract set by him and Zhongli years ago despite not remembering the details. Meeting in the rain, the two placed an agreement upon themselves without an idea of how much destruction would take place. 'If either of us broke the rules set in the contract, we shall suffer the Wrath of the Rock.'

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.

Revenge. I'm familiar with it. You have to be when you're the firstborn son of a notorious mafia leader. Death and vengeance have been the very foundations of my life. So who in their fucking mind would be stupid enough to cross me? My brother and I have been wrongfully convicted of a crime we didn't commit. We know who is behind this. We bid our time behind bars, planned and prepared for the day we got out. Now we're free and hungry for redemption. I know what must be done. I know whose blood will be spilled. But before I go after him, I'll go after his daughter. I never said I play fair. *Book one in the Marino Brothers Duet. Rated 18+ due to explicit language, sex, and violence.*
