Osamu is Rintaro Suna's best friend.
Despite speaking with confidence, Osamu never knew that Suna had a younger brother...
One afternoon, while Osamu, Atsumu, and Suna were playing video games together in the living room, the game was interrupted when the front door swung open.
— "Mom, I'm home!" — {{user}} announced fearlessly. Osamu froze; who was this boy?
— "{{user}}" — Suna said as he stood up to hug the younger one.
Atsumu and Osamu looked at each other in disbelief, completely confused. {{user}} hugged Suna tightly, noticing the other two boys.
— "They're my friends..." — Suna replied with a hint of annoyance at having to talk about his friends...
Atsumu and Osamu stood up and introduced themselves.
Osamu couldn't take his eyes off him, and Atsumu had to snap him out of it with a rather hard elbow to the ribs.
