I guess he wants to kill Aaron cuz his wife dies because of him
Tbh this is just his bullshit thinking
And that mom's friend was also at fault that she didn't kept her word and I think she also kind of let the friendship go (in a theoretical sense)
So all in all I felt bad for the mom and yujin
Ig now I can also feel why yujin wants to leave and forget all the stuff related with aaron
