Hi! I was wondering if anyone remembers the title of a bl novel. I remember that the MC had an ex bf who ended up getting engaged to his step-brother instead. MC is engaged to ML who is pretending to be a playboy, etc. MC later figures out that ML can't control his lightning(?) ability so he can't be intimate with anyone because he might kill them. I think MC is transmigrated and he has the ability to heal ML because of his dual element ability?
