I think sohoo's mom is not that pure.. she just want like to manipulate (her husband) and merry's parents r in the way?
From what I gathered from the available chapters. Merry’s father found incriminating evidences on Madame Director (sohoo’s mom) activities. She had merry’s father killed on the day of Sohoo’s birthday. Sohoo’s father found out that it was her wife’s fault and because of that felt guilty until he died. Sohoo’s father took upon himself to take care of merry and his mother which is one of the reason Madame Director hates them. She felt like they stole her perfectly crafted son and husband.
So why does the mom hate Merry’s mom so much ? Did Sohoo’s dad have a crush on the mom or Merry’s dad ? I’m still confused as to why I see that Merry’s mom stole her husband that’s why she wants merry dead.
