Looking for help

Can someone help me, I'm looking for novel or manga or manhwa doesn't matter if BL or normal. {Except yuri)
Where the MC has extreme hatred and angry towards ML because of male lead mistakes that they run aways or quit everything and completely change themselves, a good chasing arc with much suffering or a complete new Male lead would be fine,
I really appreciate if you give me a list. As many choices as possible coz i think i have read some

Thank you
