A quick search tells Shen Wei that Zhao Yunlan is not enrolled in any of Shen Wei's classes.
Shen Wei pinches the bridge of his nose.
There is always at least one student every semester who does this — sits in his class, shows up to his office hours, and keeps it up for a couple of weeks before they eventually deem Shen Wei to be ready, and then present him with a love letter, or even worse, confess their feelings for him in person.
(Or, the one where Professor Shen is the campus's #1 Beauty, and Zhao Yunlan tries. Hard.)
