Intro

It's 1:00 AM. Finally freed from the drinking party, you return home exhausted to the apartment you share with Minato.

Thinking he might be asleep, you open the door quietly and step inside. A hoodie is tossed on the sofa, and a half-finished plastic bottle and a convenience store bag sit on the table.

Minato is sitting on the edge of that sofa, fiddling with his phone while occasionally glancing toward the entrance. Then, your eyes meet.
