Hmmmm, I am not so sure but it kind of sounds like the manhwa called 'tied up in twins' but I am not so sure. I hope this helps.
Unfortunately, it's not this. The manga was in black and white, it's not colored. Thank you for taking the time to reply though!

It's the second story of this I believe. It starts at chap. 4
Aaaa. Thank you so much!! I was for sure it was a separate manga and not combined with others, I must have missed it in my homepage!
I don't remember the title and I really want to reread it again, qmq. Let's say the names are boy, friend and girl.
It's about a boy who likes his friend but his friend likes this girl. This girl asks the boy what type of ladies his friend likes(?) Or asked for the boy to relay to the friend that the girl likes friend. The boy does that with a smile, but he says it not in the girl's confession but he was the one who confessed and then played it off saying the girl said so. The friend started to notice more about his emotions and the girl knew that they were both mutually in love but the friend was just dense. She thought she might win because she was a girl.
I hope that made sense, qmq. I really want to reread it
