Hi so I was looking for a bl that I read where the mc is a guardian angel and the ml is the one that he's guarding but the mc fell in love with him. And the ml is in love with his best friend. I can't find the title
Not a guardian angel, but could it have been this one? Kinda sounds like it.

I hope the ending of this is simillar to "one-way crush" cause i get the same vibe.
