Lol you're describing practically every high school bl I've read, though I can't recall anyone right now... x))
Protect your purity! , maybe?
Lololol I remembered this one:
https://www.mangago.me/read-manga/from_points_of_three/
recommend bl with this plot
love interest is interested with the mc but a rival appears wherein the rival likes the love interest buttt as the time went on, the rival is starting to like the mc
so basically a love angle(?) turned into love cone/triangle
