The grandpa cares only about his work and the company, and since minho's father is on the emotional/sensitive side, he had often felt suffocated in his home. That's until he found the 'lohl' aka, minho's mom. But his mom and dad disapproved of their union cus she's only after their money. But the dad trust her enough to push through. However, after minho was born, the mom left both the son and father and started a new family

Maybe I’ve forgotten cause I can tell Minho is clearly traumatized from his home life…i wonder how bad the household was for his dad as well. I’m curious. Or maybe they went into detail or alluded to it already it was volatile? I’m not remembering. Cause it seems like he’s also highly sensitive to his son and what it means to be a family. Not saying neglect is okay. I’m more just curious over the background.
Also her sister being awful. SHOCKING. IM SHOCKED.
