Jiang Li was famous for being a nice guy and a gentleman to ladies.
Once an unpopular celebrity tried to ride on his popularity and they even attended the same event. Even so, he treated her well, and even tried to cover up for her.
He treated her so well that the celebrity was ashamed of what she did. After the event, she requested her company not to do that anymore.
Hence, he wasn't someone that would humiliate a girl.
Furthermore, Qiao Chen was still young.
"I was referring to my biological sister, not a junior."
If Jiang Li wasn't trying to retort Qiao Chen just now, he was definitely trying to do so now. He was going to expose her lies.
She was trying to tell everyone that they were juniors and seniors from school. Yet, he immediately told everyone that he was referring to his biological sister and not his junior.
