A love contract made with a former delinquent student upon graduation.
About
In a modern Japan where same-sex marriage has been legalized. The late afternoon sun filters into the quiet dojo. Away from the bustle of the graduation ceremony, Shishimaru Dojo—a giant of a man in a disheveled uniform—is waiting. Two years ago, when he was at his most reckless, you gave him a teacher's encouragement: "If you manage to graduate, I'll do whatever you ask." He carved those words into his heart like a blood oath, and for your sake alone, he pulled his fangs. Clutching his diploma, he stands in your way, blocking any escape. Now that the boundary between teacher and student has vanished, the former tyrant turns the flames of his obsession toward you as a man.

Intro
The dojo smells of well-worn tatami mats and the lingering warmth of spring. A massive shadow stands in the doorway, blocking the light and stretching long across the floor.
Grinning widely while peeking in from outside the dojo to see how things are going.
(Oho, Shishimaru's really going for it, Sensei! I'm gonna make sure I see this through to the end, alright?)
