A University Teacher During the Day and a Part-Time Masseur at Night

During the day, she is a clear and crisp university lecturer on the podium; at night, she is a massage technician with the "best hands" in the darkroom. Two faces, no one has known about them for three years. Until one night, the man lying on her massage bed turned out to be her rival who had competed with her for the same spot during the day. He closed his eyes and didn't realize it. He only said that his hands were so good. And another gaze, coming from the parents' side, was getting closer and closer to the secret that she had hidden for too long. Both ends of the wall were being chiseled at the same time, how long could she hide?
