Draco fell first and is good at hiding it

Anyone have any fic recs where Draco is friends with the Golden Trio and had been in love with Harry for a long time, but has come to silently accept that nothing more than friendship will ever happen between them. This being something he accepted awhile ago so he's managed to hide his feeling very well as he hangs out with the Golden Trio and none of them notice anything.

Then Harry ends up falling for Draco and starts acting like a bumbling pining idiot around him. Draco notices Harry acting strange around him, but he's oblivious as to why, not at all considering Harry had fallen very in love with him too.

Maybe Hermione and Ron try to help Harry try to seduce Draco, but Draco is used to holding back and hiding his flusteredness whenever Harry did anything to make his heart skip before Harry realized he was in love with him, so none of Harry's attempts seem to have any effect on Draco. Harry feeling very dejected because of Draco's lack of reaction, thinking that Draco can only see him as a friend.
