Hold the flipping phone, in their reality they are "normal" people, this isn't a dark romance mafia manhwa where they can just murder ppl in broad daylight. He's doing what he can obviously with his small small power and to protect not only haebom but his friends and family from the old bastard, take it with a grain of salt and wait it out, justice WILLLLLL be served no matter what
Hell nah I'll be serving justice and time, even if I lived in hello kitty world, or Teletubbies world if my partner was getting rape threats because of my fuck ass grandpa I'm gonna pull out a fucking machete and end that bitch . I would go to jail for my partners life n dignity and in broad daylight. Ya try me gramps

Ngl if my fuck ass grandpa threatened my partner and subjected him with kidnapping, rape threats, and more . I would skin that old ugly bitch alive. ML isn't doing enough
