@OpalEyes i didn't fully understand the raw chapter but i think sejoon's father don't want to sell something and mr.kwak father got angry and he plan to put mr.kwak in sejoon's family they adopt mr.kwak when he was a kid not knowing that he is a son of that guy and they really good to mr.kwak so mr.kwak felt really sorry for them so he run but his father catch him and he call sejoon's father he tell them that they kidnaped mr.kwak so sejoon's parent go to rescue him but they got into an accident ..
