I saw it a while ago, but I can't remember the name kf it. And I only remember a rough summary ╥﹏╥
It's abt MC who is crushing on his classmate who is chubby.
Then a timeskip happens and they meet again where he is no longer chubby but considered hot? And MC is sad about that fact because he liked him better before?

I know that's not an uncommon trope, and I already checked out some lists but I still have trouble finding it. I'm also guessing the manwha is unfinished or won't have toooo many chapters out yet bcs it seemed rather new when I heard abt it?

Thanks in advance!ヾ(❀╹◡╹)ﾉ~

Edit: it's probs korean and in full colour
