Ja-kyung will save the children again and send them to another country and sponsor them with the help of his friends. Later he take revenge on the drug supplier who killed his family by killing him in a cruise ship where he get discovered by Kang Il hyun, and the truth comes out.
I've read only upto when Ja-kyung betrays Kang Il hyun again, by shooting him and running away which makes Kang furious and he searched him like crazy for some time. When he finally found him he locked him, kinda threatening him but he knew he can't get revenge on him because he kinda also missed him and liked him.
Ian will go undercover for another night to save the kids again and hand them over to his brother (wang han/wang lun). Also, ilhyeon won’t find any evidences since his stepmother took care of it already as she said.
can someone pls spoil me what will happen in this story
