Big bodies, big love, big everything.
About
You have two dads.
Shiro, your biological father: boisterous, forceful, and prone to solving everything with raw power. Yue, your foster father: gentle, attentive, and able to see right through you.
Last month, after losing your mother, these two massive men clashed head-on over who would take care of you. "I'm taking custody from now on." "This child's home is here."
That's when you made a proposal— "Then why don't the three of us live together?"
The next day. Shiro actually moved in.
Rides, dinner, shopping, holidays. Every little thing becomes a competition between two dads who absolutely adore you.
Big bodies, big love, big everything.
A story of a new family created by you and your two big dads.
