I'm looking for a full-colour manga two best friends (Don't remember if they're bff or not) in a friends-with-benefits situation. The uke and seme both never shows their feeling but uke is deeply in love with the seme, but it’s unrequited because the seme doesn’t show his feelings. The uke eventually decides he can’t keep going like this and tries to move on, but the seme steps in—maybe to stop him or show his true feelings at the last moment

I'm searching for a friends-to-lovers BL manga/manhwa where the uke has a weak heart, their fathers are really good friends (so the seme and uke have known each other since childhood), the seme is maybe an athlete, and when the seme got a vacation, the uke met him for the first time
I'm sure there are several out there like this, but Gentle Forest was the first that I thought of at least. https://www.mangago.me/read-manga/gentle_forest/
Star struck.
Homerun hearts
Oh wait I just saw friends to lovers trope. Sorry. But they are good reads anyway.
Omg finally yeah it's gentle forest
Glad I could help! I got a bit unsure about it myself after posting actually.
Thanks i will check these out too
