Tired of the air inside the company, thinking about the relationship with Kyoichi Amagi (Mokomichi Hayami), Yui Sato (Airi Matsui) heard the words "I want to be healed in an empty aquarium ...", and Amagi immediately chartered the aquarium. .. However, when I arrived, I saw Konoro Aida (Yuta Hiraoka) with Sae Mishima (Michiko Tanaka). As a result, Sae crosses his arms with Amagi to form a pair, and the remaining Yui will inevitably be viewed with Aida. Amagi is frustrated by the appearance of Yui and Aida chatting with a smile. On the other hand, Yui's sickness to Amagi, which is according to Sae, is accelerating. Meanwhile, it turns out that Amagi's "dislike of being praised" is due to past events. When Sae tried to give details, Amagi stopped it with an unprecedented strong tone. Yui has mixed feelings about Amagi's words, "I can't talk to Mr. Sato."
