Osamu thought it was stupid and that he should not get riled too much by Atsumu, especially if it seemed like an elaborate way to embarrass him, but pride is such a powerful thing that he found himself in the situation:

Atsumu noticed something was up. He had more than just an inkling feeling regarding his twin's affection for their friend.

Rintarou always have this habit of stretching, at first it was to make sure his core would be fine and he did enjoy how his body felt after.

“Do ya ever get tired?”

Rintarou looks up from his phone, and titled his head, “What do you mean?”

“Of ma face in yer phone—probably have tons of pictures,” Osamu mumbled. He blushed at the reminder of just what types of pictures Rin has—the candid ones, the blackmail ones,

When the air feels a bit too sharp, Rintarou feels his nerves jitter,

The preparation for Osamu’s birthday was coming near, and while the twins opt to share a birthday together—even if they said that last years was their last—

One autumn morning, Rintarou was on his way out of the apartment. As he opened the door, the morning breeze raced into the genkan and sent a concentrated cold chill on his face—stopping him from stepping out of the room,

He was able to shut the door close but the shock left him

Osamu asking a needy Rin—rutting against his foot while his arms are wrapped around Osamu’s leg—if he still has bitchy remarks left inside pretty lil’ head or has it all been emptied out when he decided to act like a depraved slut and came all over Onigiri Miya’s freshly clean—
