This is likely to be a short story, a burst of inspiration after M29. I'm starting with no audience, so please add it to your favorites!
Blurb:
Reiko discovers that life after transferring schools is full of surprises. She finds a new family, new friends, and great success in her studies and finances. The only downside is that she's been left eating her words.
Before they parted, she promised her blonde, dark-skinned friend and her blue-eyed, catlike friend: "I'll focus on studying after I transfer. I absolutely won't waste time dating."
When they meet again, Reiko takes the hand of the curly-haired boy beside her and introduces him solemnly: "This is my boyfriend."
Matsuda feels that ever since he met a certain pink-haired girl, his once peaceful, monotonous school life has suddenly changed its tune.
He somehow gets close to all sorts of people and somehow finds himself taking part in all kinds of activities. But what surprises him most is that he doesn't mind any of it.
At last,
Matsuda announces to everyone: "Yes, we're together."
In response, the entire school cries out in their hearts: What?! You only just got together now?!
P.S. OOC warning! This is my take on Matsuda. Matsuda-Chihaya shippers, stay away! There will be a scene where Chihaya clearly turns him down!
Premise: Becoming a better version of yourself
