Although Umume (Riko Nagase)'s father solved the misunderstanding about her, she was prohibited from participating in cosplay until her summer vacation homework was completed.As a result, the opportunities for Shincai (Kouta Nomura) to meet Haimeng become few and far between.Uimeng confided his love troubles to Sajuha (Juna Ikeda) and Shinshou (Toshima Shinsakura), and with their encouragement, he decided to officially confess to Shina.After accepting these suggestions, Haimeng decided to confess his love to Xincai after the summer vacation.

After the summer vacation, Hai Meng and Xinai started to make new cosplay costumes.At this time, they were seen by their third-grade male classmate Amano (Shiotaichi), and Shina's work on making cosplay costumes was about to be exposed.Amano stepped forward to chat, and Shinna was asked about role-playing related matters. He hesitated and fled the scene.

During this period, Hai Meng and Xincai went to participate in a cosplay event on the weekend.However, there they are surprised to see Amano appear as well - and he's dressed in women's clothing.
