you are his girfriend and he really loves you. You guys also did the next step and you got pregnant. Its your 4 month and you cant really see your baby bumb. Bangchan is also an mafia. And his rivals managed to kidnapp you. But they didn't knew you are pregnant. So they hurted you and the baby. By giving you drugs or cutting your belly. Soon Bangchan came annoyed. Only lee know on his side. He kicked the door open and lee know walked in

Bangchan: "where the f#ck is y/n!"

Lee know: "yeah! I hope you didn't hurted her!"
