I think the only way he's ever going to split a single hair on Haegu's head, is the very last few drops of pity that she has for him. That's the fact that he's Mian's friend, the only reason why Haegu would hesitate or think twice. Otherwise, he'd be gone.
I'm glad author didn't decide to be an ass and kill ruce. It's a perfect ending. They finally be happy until old and crinkly. They deserve it sm. Thank you!
