Can someone recommend me some manhwa/manga/ manhua with satisfying chasing arc , redemption and lots of yearning, where ml/mc even beg for their lover to love them or to stay with them. I will read anything be it straight ,gl or bl . If there is enemies to lovers trope it will be chef's kiss.
I'm not sure whether you're looking for BL/GL/straight ones; but here's some famous BL recommendations you might like-
