I remember i found a manga back in middle school and i absolutely loved it, i need help finding it again!

I remember it was a highschool romance (it was a comdey too i think but had some pretty serious moments as well), it was mostly from the girl's side, the male lead was a very tan, he was somewhat of a delinquent, I definitely remember her dad was a pro wrestler.

Im not sure if this helps but I remember one story arc the dad wouldn't let the boy see the girl so they snuck letters to each other.

Sounds a lot like Junai Tokkou Taichou!. Hope that was what you were looking for!
