Although the ambiguity between Kaili (Yuta Tamamori) and Yui (Sae Okazaki) is always on her mind, Honomi (Nao) still works hard on boxing training.At this time, Yui announces that she will be Kaori's (Mizuki Akada) second assistant for the competition.On the other hand, Nao noticed the complicated expression on Yui's face and guessed that it was related to what happened seven years ago, so he wanted to talk to Yui, but Yui ignored him.

Reluctantly, Suomi follows Yui for a run.Perhaps because she felt that Suomi was too persistent, Yui began to talk about why she became a coach and why Kaili gave up boxing.At the same time, Suomi also understood how important Haili was to Yui, and her heart became mixed.It turned out that Haili had refused to box since the accident seven years ago.

Kaori's fight date is set, and Yui wants to change Kaori to invite him to watch the boxing match.She believes that if she can participate in the competition as the second assistant and show Haili that she has transcended the past, she may be able to make him change.

Suomi learned that Yui had this idea and wanted to help Haili.Will Haili accept the wishes of these two people...
