Amagi immediately leases the aquarium after hearing the words "I want to be healed in an aquarium with nobody ..." , from Yui because she was tired of the air inside the company and considering her relationship with Kyoichi Amagi (Makomichi Hayami). However, when they arrived, Kotaro Aida (Yuta Hiraoka) along with Sae Mishima (Michiko Tanaka) were there. As a result, Sae holds Amagi's arms, and Yui was inevitably watched by Aida and the two of them. Amagi gets frustrated by Yui and Aida chatting. It turns out that Amagi's "praise and dislike" is caused by past events. When Sae tries to give her the details, Amagi stops it with a strong tone. Yui has a complicated feeling for Amagi's words, " Sato-san doesn't need to know."
