When Taichi (Kobayashi Toranosuke) heard Xi (Ikeda Ryo) talk about the original intention and experience of founding “sig-n”, Xi's words revealed his persistence in dreams and expectations for the future, which made Taichi involuntarily think aboutto the time spent with Kohei and the influence Kohei had on him.

Although Taiyi has unraveled the meaning of Hangping's sign language when they parted and understood Hangping's thoughts, he is caught in contradictions and struggles in his heart.He is eager to reconnect with Hangping, but also afraid of facing possible changes and uncertainty.This complex emotion made Taiyi feel helpless and confused, and he didn't know how to take that step.

In this state of mind, Taichi accepted the invitation of Yokoyama (Usa Takuma) to participate in the summer festival.He hopes to temporarily forget his inner troubles through the lively festive atmosphere and soothe his mood.However, fate arranged for him and Hangping to reunite unexpectedly at the summer festival.

The moment Taiyi and Hangping's eyes met, his heart jumped suddenly, and all his thoughts and emotions rushed into his heart in an instant.He felt surprised and nervous, and at the same time, there was an indescribable joy deep in his heart.This unexpected reunion made Taichi realize that his feelings for Hangping had never really gone away.
