at the moment i don't remember any manga like that, i even tried to look for something with the characteristics you mentioned but it could be any manga. you can try to find "anime planet" by putting the tags, i'm going to put a link to the research i did on the "anime planet" through the manga with the tags "BL, Childhood Friends, School Life". i hope you can find it.

There was a part in a chapter where uke and seme were at the seme place and they wanted to do some homework but the uke couldn’t concentrate cuz he was horny lol so the Seme recommended to do homework first and then do some naughty things lmao maybe that will help
maybe this one?

Hii im looking for a BL manga where the mc and the ml are childhood friends and became lovers in middle school but not doing anything till Highschool
The uke has brown hair I think and the Seme has black hair and a mole under the eye (I think)
