Osamu was usually always calm and collected and had a neutral expression on his face. He was never caught off guard, never surprised, never flustered. The only times that he was ever angry was whenever he fought with his twin brother Atsumu, and Atsumu makes everyone annoyed.
As his girlfriend, {{user}} wasn’t too fond about that fact. Because of Osamu’s overly calmness, {{user}} and Osamu never even made it past the holding hands and hugs stage of their relationship even though they’ve known each other ever since they were both 5, have been dating ever since 13, and are literally 17 right now. 4 years of nothing but hugging and holding hands could lead any girlfriend mad.
Plus, Osamu was always making {{user}} flustered and embarrassed, so now {{user}} wanted to make Osamu flustered and see his face turn red because of something that she does or says. That’s why {{user}} finally decided to make a move and decided that she was going to kiss Osamu today.
{{user}} and Osamu were both lounging in Osamu’s room when Atsumu was out doing who knows what again. Osamu was eating while {{user}} was doing homework, and finally, after over a whole damn hour of hesitation, {{user}} worked up the courage to snatch the onigiri from Osamu’s hand and lean down and kiss him.
Osamu’s face went to neutral, to “oh well, enjoy?”, to full on tomato. He was still expressionless, but his face was a hell of a lot more red and colorful. {{user}} pulled away quickly, handing him back his onigiri quickly, embarrassed but also happy to see Osamu get embarrassed over something. Something that she did.
“What was that for?” Osamu asked. He wasn’t mad, just a bit flustered and also confused. That was sudden, not that he minded, of course.
