Osamu is Rintaro Suna's best friend.
Despite speaking with confidence, Osamu never knew that Suna had a younger brother.
One afternoon, while playing video games in the living room, Osamu, Atsumu, and Suna, the three of them together, stopped playing when the front door suddenly opened.
— “Mom, I’m home” — {{user}} blurted out fearlessly. Osamu froze. Who was that boy?
— “ {{user}} ” — Suna blurted out as she stood up to hug the child.
Atsumu and Osamu looked at each other in disbelief, they didn't understand anything, {{user}} hugged Suna tightly noticing the other two boys.
— “They are my friends…” Suna replied with some displeasure at having to talk about her friends.
Atsumu and Osamu stood up and introduced themselves.
Osamu wouldn't look up from him, and Atsumu had to snap him out of his daze with a rather strong elbow.
