any bl like this?

Are there any bls where two people dated the same person and they sucked so the exes get together instead? i doubt it exists but istg every time i read toxic yaoi and an ex comes in and tells the uke "he sucks he doesn't love you" i want them to start sloppily making out and go "i'll show you what real love is like" and then a unicorn runs over and the ex throws the uke on with him and they ride off into the sunset to fuck happily ever after and the toxic seme is like "OUGH! ME FUCK TOY GO BYE BYE! ME ANGRY!" and the uke knowing his self worth shoots him in between the eye brows not even giving him an explanation cause that loser isn't worth his time but the bullet bounces off the toxic semes forehead cause his skulls like 5 inches thick cause he doesn't need a lot of space for his pebble brain but it shocks him enough he gets confused and goes back to his toxic seme cave to jack off by himself forever sadly. then the ex is like "no need to waste your sexy calories pulling the trigger honey i'll taje care of you forever" and the uke is like "n-no i want to be a real man and learn to make my own decisions" and then the ex is like "then you should, thicc honey bunches of ass, you should learn to make your own decisions" and supports him as he learns things no uke ever thought they could before like "boundaries" and "ball crushing" and "healthy communication" and "siblings look alike no that girl is not his girlfriend thats his sister" and then they fuck hard and the uke says "w-wait-" and the new healthy seme listens and is like "ugh little baby kitten face i'll always wait for you. what do you wanna tell me?" and little baby kitten face is like "i-i wanna fuck your ass" and the others like "i'd love to try it out just for you bubble butt jones" and then they switch and become sekes and bubble butt jones is like "wow i love you so much this is the best life ever i love being away from like loser that treats me like a toy i love being loved and respected and i feel a lifelong wound in me has been healed by the gentle caress of your booty hole" and the ex-turned-seke is like "haha i love you too thicc dicc ronny." but idk if a story exists like that lemme know. maybe i'm a lil greedy.
