Donghae, who was also a member of the dance club, told Heechul that he had figured out that the perpetrator will attack the victim near the garbage dumping ground between 9 and 10 pm at night. When Heechul went to the said place, he came across Kangin. It turned out that they both have the same idea. Meanwhile, Donghae who was tailing Kibum, called out to him and accused Kibum of being the culprit. Donghae deduced that the reason that there was no attack being carried out on 14 May is because they were held back by extra classes. Kibum admitted his fault but instead of exposing him, Donghae proposed an alternative plan.
