Okay I remember there was a manga I read and I don't remember the name but there was multiple chapters. I believe there was a couple chapters dealing with this same couple that I'm looking for.

In the beginning of this couple's story, the main uke is a helper of a basketball team and all he does is pick up the balls during practice and cleans up I think. He may or may not have a crush on the captain/ace of the basketball team. One day he catches the captain (seme) with the vice captain (uke) doing the naughty. The main uke leaves and the other 2 knows he caught them. Later on in the chapter the captain invites the main uke over and when the door is opened and the main uke saw the vice captain he ran away. Of course the captain chases after him and they do the naughty thing in public I believe and end up as a couple.

Then a couple chapters with different couples and I think the last extra chapter is about this same couple again but in the school showers with small drama about the captain graduating I think and leaving?

Is it the first story from Omoikkiri Suki ni Natte!?

Oh yes it's the one! Many thanks! 😀
