Why is everyone so mad about the grandma sublot, i think its a nice subplot for the webtoon that will touch upon different topics. Idk i kinda pity her cuz yes she did a lot of mistakes as abandoning her son, but she was also young and stupid in an abusive domestic situation and desperately needed to escape. Hyesung has grown and healed now so its alright if he decides to forgive her or not. And the the family that she remarried into left her as well kids so shes completely lonely so its nice dojun is financially taking care of her, would just preferred if hyesung would know. But im guessing this all is gonna cause lots of fights and drama when revealed but then when tf did ppl start hating plot?? and last argument, dojun made big mistakes and was forgives and as well hyesung, why cant she?
