Hello!
I have been looking for this certain BL manga that I read a while ago.

The plot is:
Bottom used to date boy A, turns out boy A’s fated pair is bottom’s best friend and boy A decided to stay with his fated pair.
In the current timeline, bottom meets boy B, falls in love yada yada. But boy B is boy A’s twin brother so they have the same fated pair (bottom’s now ex bestie). Boy B is able to defy his fated pair blah blah and stays loyal to bottom.

I hope my summary makes sense. Please, if anyone knows the title of this manga, send me the link

Thank you
