@Readamangareader123 same doubt...
@Readamangareader123 as his child. Since they can’t legally marry in Korea. If I had to guess he wants a legal way to give his assets to Ho and Sol in case anything happens to him
@Readamangareader123 Thanks for the input @Woojin stan account. And it will also help incase of any medical emergencies.
