So when Cirrus mom passed away his dad rlly tried to make things work being a single dad and taking are of cirrus on his own but cirrus being a child wanted his mom so basically kept crying a lot almost everyday and fighting his dad which led his dad to have a breakdown and started drinking more alcohol then when cirrus went to check in his dad he saw his dad begging to the dead mom that he wished it was cirrus who died and the dad saw the son so after that incident thats when the dad started to lose emotion and care for his son and start looking for other women to compensate the loss of his wife which further increased his lack of emotion for cirrus
I am re-reading this. Somehow why do I think that Cirrus' stepmother is pregnant? There is a chapter around Chapter 50 or 60 where Cirrus ask why both of their maids/helpers are in the house and the maid said that the chairman (Cirrus' father) wanted his stepmother to be comfortable at home. I have this thinking that his dad got angry at him (punching him) in front of the school because Cirrus tried to strangled Jisoo when she is pregnant. It maybe the reason Cirrus' dad easily let go of Cirrus to move out of the house. How can he choose the stepmother instead of his biological son?
