he probably doesn't, i remember him telling gok in the previous chapters (where bin and gok were the main couple) that after the child (aka hwa) grows up he wanted to spend his time alone with gok so yeah ig now he feels he won't be able to do that for a while(￣∇￣")
Yeaa he probably still doesn't care that much for the grandchildren. It took him some time to really care for hwa back in season 1.There was also a chapter where he told the elder that he only cares for the safety of his family, meaning gok and hwa, and not hwa's partner or the triplets inside him. Still love bin tho. ╮(￣▽￣)╭
It’s like bin doesn’t give a fuck about anyone else other than gok like not even the children
