Lin Chen recently discovered that his takeout always mysteriously went missing. After investigating, he found out that this was all done by his dorm roommate Sun Peng. Lin Chen and his good brother Cheng Yu wanted to go to the counselor to get an explanation, but unexpectedly, the counselor not only refused to care, but instead lectured him that suffering a loss is a blessing. Therefore, the two had no choice but to guard their personal belongings strictly. In return, Sun Peng intensified his actions. In the end, Lin Chen no longer cared about roommate friendship, and made both the counselor and Sun Peng receive the punishment they deserved.
