I never agreed with the view that stockholm syndrome or lima syndrome was occuring for Bum or Sangwoo. I think it could be considered Stockholm syndrome if Bum any way justified the abuse (i.e. blaming himself for it or saying it's not Sangwoo's fault) but he hasn't done that yet. I also think Bum stays with Sangwoo because he's given up of leaving not because he wants to stay like many victims of Stockholm syndrome. Technically it could still become Stockholm syndrome even though Bum fell in love with him before being captured. Then it would be similar to trauma bonding in domestic violence relationships.
