In the novel, he regains his memories back! He hides it from her and reverts back to being a sociopath. Basically, he ruins the competition for her, vandalizes her home, mentally, physically, and verbally abuses her, and leaves her while she is begging him to stay even if he hates her. The cherry on top is when the villagers mob assault her (because he killed her tree from the competition) and he just watches.
We shall have to see if the manhwa goes the same direction or take liberties to make the ML reedemable for fans reading the comic.

My heart can’t take it now that we’ve finally gotten here. I’m not ready for the switch to flip
