I'm going crazy because i can't remember what manwha this is but I remember this one scene where the Dad of the MC was trying to find a ledGer. I think the MC was looking for the same thing (not 100% sure).
Anyway, the farther eventually gets the ledger (i think i remember it was buried somewhere close to their old home or something) and gives it to some bad guys and right after he gave them the ledger he was hit by truck on purpose to cover up their tracks or something...
I know my memory is all over the place with this one but maybe some1 remembers the scene and knows what I'm talking about :'(
