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/
Now im scared for the next chapter
