When En Jie and Hannah saw Tae Jun and JaeHee fall together, Hannah became suspicious of JaeHee and asked the staff to investigate JaeHee. En Jie told JaeHee that he and carrot started dating. Tae Jun thanked JaeHee for his sacrifice (attending miss genie). Due to the reorganization of the first dormitory, three people have to live in one room. In exchange for the opportunity to go to JaeHee's dormitory with a signed football, En Jie officially moved into the dormitory of Tai Jun and JaeHee and started their lives. JaeHee still didn't give up looking for the necklace in the swimming pool. En Jie learned that the necklace was very important to JaeHee, so En Jie worked hard to find the necklace, but after knowing that it was Tae Jun's necklace, JaeHee was so nervous and concerned, he didn't give it to JaeHee. En Jie and JaeHee are very happy in the dormitory, and Tae Jun feels left out. JaeHee was cheated, thinking that the necklace would be demolished in the art building the next day, and rushed to look for it overnight. Although she was not scared by the female ghost pretended by her classmates, she was locked in the art building. Fortunately, Tae Jun found her and rescued her, and they had a heart-to-heart talk. Tae Jun learned of JaeHee's birthday and bought her a present. En Jie also knew JaeHee's birthday and decided to give the necklace to JaeHee. He could no longer be confused and decided to treat carrots wholeheartedly.
