But you have probably already read that, hmmm
This reddit thread mentions a few reccs out of which I remember Last Game being a major rivals to lovers story

This author is obsessed with overtly kind and selfless ukes who basically border on being pushovers (actually in the author's other two works, they are pushovers), and semes who are psychopathic or really lack empathy and are also handsome but only love the ukes because they are just so special in their kindness or doormat-ness and no other person is like how kind and selfless they are. And therefore the seme is now a sociopath because they have some semblance of empathy (possessiveness, I don't think you can call it empathy) because they can love but they are only capable of loving the uke
