Namcha followed Jin and found Irin. They had a conversation about their future. Irin asked Namcha to marry Inn. Namcha saw Jin when he left Irin’s room. He invited Jin to drink in a bar. Inn called Jin and found Namcha was drunk. She tricked Namcha and made him think that they slept together, then told Grandpa she was pregnant. Grandpa did not want his reputation to be ruined, so he wanted Namcha to marry Inn immediately. (Source: Viu)
