Just a weird hunch, theres no way he'd just dissapear like that out of the blue for 6 months
Or GP had something to do with it “here a billion, leave my grandson alone” kinda situation or blackmail
Id agree but it was shown with the dad that haebom doesn't take money like that so probably blackmail
If it’s not any of those three and heaven is just on his period imma be pissed at author-San >:(
