The Instructor's Tacit Consent

During the September university military training, 19-year-old freshman Gu Xin falls for 23-year-old instructor Lu Shuaijie at first sight and deliberately soaks her training uniform to get close to him. Their relationship escalates from a restroom stall and posture drills at the back of the formation to using a key to enter the instructor's dormitory at night. Against the backdrop of military discipline and their status gap, Lu Shuaijie goes from never stopping her to actively setting traps, and the two embark on a forbidden, increasingly intense push-and-pull of desire.
