Li Lanni didn't know what to say to her mom, so she fled to her room.
Once she left, Li Yuming shot Ji Xiehan a look of disapproval. "I know how you feel towards my Lanni, but it doesn't mean you can take advantage of her. I don't want any shady business."
Ji Xiehan felt awkward. Without a doubt, the 'shady business' Li Yuming was talking about was obviously premarital sex and having children before they got married. Having such a discussion with his mother in law was really... "Auntie, I understand. I will only be with Lanni when she's my wife."
Li Yuming was pleased with his confident and genuine answer, and she even invited him in for a drink. Of course, she would. She liked Ji Xiehan as she would like her own son. She was even happier that he was going out of his way to ensure Lanni's safety. So she didn't have anything against him getting close to Lanni as long as he didn't do anything to hurt her.
