the thing woman is or general thing you want to see in your partner are their personality(through their past, occupation etc) so if i was in gonda shoes i will probably postpone it to get to know her better. single mother or no if her personality 10/10 it doesn't matter.
using mc iq to show his capability while he is being clueless to the situation when he get transported though elaborating how he kill 15 people will be good. at least its not some funny super power shit
in the girl perspective if she dont know who he is that creepy as heck never mind even if she know him if he is not handsome she will still think he is creepy
