In his memory, he clearly didn't know of this woman's existence, but because of this sentence, his heart suddenly felt like it was being tugged at by something. He felt it, a heartache that seemed never to have happened before.
Besides anger, there was indeed heartache.
At that moment, he mistakenly thought his stomach ailment had flared up.
He took a lot of stomach medicine, even had breakfast, but the pain there never eased. Instead, it became even more intense because of the scene where a man said, "I am madly in love with Qiao Xiguan," and Qiao Xiguan's face turned red.

To him, she was all thorns.
He really didn't know if the former Qiao Xiguan was like this too, or if it was just because Qiao Xiguan couldn't stand the fact that he had forgotten about her.
