This is the most that I can remember from it:
It’s a BL book (obvs) with the male MC fantasizing and adoring his two male neighbors who happen to be super rich and movie stars (or singers I can’t remember). Those two neighbors are in a relationship that the MC doesn’t know about but after going to their house he’s somewhat seduced and enters the relationship.
What the MC doesn’t know is that the main ML (the Top and the one who ends up with the MC) has liked him for a long time and is only using that situation to get to him and claim him for himself. The second ML (a switch) doesn’t like this and tries to ruin their growing relationship because (I think I remember) the main ML tells him that he doesn’t like him and never did. Something happens and the second ML frames the MC (I think he took pictures of him and the main ML doing something) and blasted it online which the MC then got ridiculed for.
The last bit I remember is that in the later chapters there is a time skip and the MC meets up with the second ML who ended up leaving after trying to ruin the main couples relationship.
• It has Smut
• It is completed but I don’t know if the website said that or not
• I read it 2-ish years ago
• It was maybe 30(?) chapters or more
• I also think that the second ML (the antagonist) had yellow/blonde hair while the main ML had jet black hair
