Manga where tall FL and bf get jellyfish hats on a date?

i dont think its lovely complex but im still gonna suggest it

To add more detail, the high school bf has an ex who draws a lot and is sorta quiet. And middle school boy makes a comeback but this time taller.

It’s not, but thank you for the suggestion

I found it! It’s called “stand up!” by yamakawa aiji. Definitely recommend to anyone who’s interested!
