What kind of stupid lie must Evil Grandpa have told Haebom to get him to agree to this corny scheme? Everyone was supportive of their relationship so there were no obstacles. He can't really threaten any of his friends or family, they're all dead or shared with Taesung and therefore physically/financially protected.
He could have made a moral accusation that shook Haebom, like maybe the boys are actually related. But that also makes zero sense, because Taesung's Grandma, Eunsun, and Silver Fox Daddy would have also known this and objected to the relationship.
