Rec enemy -> lover Bl

So I'm searching for enemy to lover bl stories, but NOT the casual "I hate him -> oh I like him"

I would like stories in which Mc and Ml are TRUE enemies because of extern circumstances (like their family, their clan,...) or their deep personal beliefs, so they struggle to accept their feelings.
But at the end, they are still drawn together in spite of everything

To give you an idea, à story like
-> "To Take An Enemy's Heart"
-> "Bad friend"
-> "The Fallen Duke & the Knight Who Hated Him"
(I dont care if it's manga / webtoon / modern / Historical / fantasy / ...)


If you have any story like that please don't be shy (⌒▽⌒)
