Cheng Xi could only reply very seriously. “Professor, I already have a boyfriend.”

Cai Yi made a soft ‘Oh’ in response as she inspected her closely. The girl in front of her had a very youthful face and was young, pretty, and filled with an exuberant vitality. This really made her admire Cheng Xi. She had known her for quite a while now: the first time Cai Yi had met Cheng Xi was when the latter was a senior in college, following behind a bunch of students doing a practicum. While the others had been somewhat frenetic and wary about the prospect of facing a mentally ill patient, she had already started approaching him.

Even after all these years, her vitality had not been depleted one bit; it wasn’t just a matter of youth, but also her passion and love towards her career.

But Cai Yi put all this aside and casually asked, “How long has it been going on for?” After hearing that it hadn’t been too long, she clicked her tongue. “You should still be in the passionate stage, but I don’t see any of that sweetness in your face.”

Cheng Xi responded somewhat drolly, “I didn’t know that you could read faces too, professor.”

Cai Yi was proud....
