After Marrying a Yandere

When I read the novel for the first time, I expected the male protagonist to explode immediately...

The heroine can't really fall in love with the hero...? 🤔🤔

This male protagonist seems to really have that serious illness (remove the appearance)

Did the male protagonist know the female protagonist before? Or is it purely love at first sight? But I didn't see the point about love at first sight (maybe I didn't pay attention...) If you have known the heroine before, I feel like you can add some hidden subplots, so that you can better understand the motivations and inner thoughts of the yandere male protagonist. If it is love at first sight, you can add some touching descriptions. Come on Gugu~
