College student Hang Ping is always misunderstood by others because of his hearing impairment. He is unable to integrate into the surrounding environment smoothly and gradually becomes alienated from the crowd without realizing it.At this time, he met Taiyi, who was in the same grade.Taichi, who has a straightforward and cheerful personality and speaks whatever comes to mind, told Hangping: "It's not your fault that you can't hear!" This sentence made Hangping feel redeemed from the bottom of his heart.However, just as the two met by chance and Hangping gradually returned to warmth, his hearing became worse and worse... Can he and Taiyi communicate before Hangping's hearing completely disappears?

Kohei Sugihara, a college student, suffered from sudden deafness in middle school. From then on, keeping a distance from others became a matter of course.One day, while preparing to eat lunch alone as usual, Sagawa Taichi, who was in the same grade, suddenly appeared.

Kohei wordlessly handed his bento to Taichi, who was fired from his part-time job and was hungry, and left.Later, Taichi learned that Hangping's hearing was not clear, so as a quick thank you, he volunteered to deliver lectures to students with hearing impairments in real time.

Taichi accepted the job of exchanging a notebook for lunch, but the writing was dirty and messy, so it was not ideal as a notebook.But looking at Taichi happily eating his bento, Kohei smiled naturally.

One day, during physical education class, Hangping's hearing aid fell off due to contact with a student, and the class was temporarily interrupted.On the court next to him, Taiyi looked happy and enthusiastic about basketball.

Kohei recalled the “discomfort” he felt when his hearing decreased...

Tai reluctantly invited Hang Ping to participate in the filming of the film research team directed by Noko.Later, Taichi learned that Yoko's cousin Miho, who also came to help with the shooting, wanted to know his contact information through Yoko, and was looking forward to it.However, when the two actually met, they were only asked about Kohei...

Under such circumstances, Hangping learned about Taiyi's past hidden in the hamburger that Taiyi said he liked so much that he wanted to get married.

Entering the testing period, the days of Hangping and Taiyi's notes were cut off.In this way, one day during the summer vacation, Kohei invited Taichi to participate in the summer festival at the suggestion of his mother Ryoko.After getting the OK reply from Taichi, Kohei became excited.However, contrary to such a happy mood, it became clear that the condition of Kohei's ears was gradually deteriorating...

On the other hand, Taichi and Miho failed to tell Kohei about a series of things that happened in the coffee shop.Then, we met the two people who were supposed to be waiting for the summer festival...

One week after the new semester starts.Hangping didn't show up at school, and Taichi didn't reply.Taichi went to Hangping's house restlessly.

Taichi accidentally met Kohei's mother Ryoko in front of the entrance, so he entered Kohei's home and began to daydream after hearing about the deterioration of Kohei's ears and the fact that he made hamburgers for himself.

Later, Taichi expressed his feelings for Kohei to Noko.Hangping accidentally heard Taichi's true words...

Hongping and Taiyi, who had successfully reconciled, decided to go camping together at Heng's invitation.

Hangping looked at the defenseless Taichi and tried his best to hide his feelings for Taichi who was growing up. However, Taichi also slowly realized what happened to Hangping after the kiss...

Under such circumstances, Taichi, who once again accepted Kohei's notes, formally accepted the lecture and worked hard while taking notes.On the other hand, I hope Hangping will also actively participate in sign language clubs.In this way, the years passed, and the second spring came after the two met.

In the new semester, Taichi, who helped the club persuade, took the opportunity of picking up a handbook for people with disabilities and met Maya Sakuragami, a new student with hearing problems.From Kohei who accidentally appeared there, Taichi learned that he was Maya's tutor. However, Taichi felt very uncomfortable with Kohei who didn't tell him anything about important things...

At this time, Heng's words forced Taiyi into a desperate situation and made him spend a depressed time.At the dinner party that was suddenly decided between the Yingyan members and the new students, Kohei saw Taichi and the girls talking happily, and confided a certain idea to Maya...

Kohei (Motoki Nakazawa) is worried that starting from the second grade, as the professional courses increase and become more difficult, helping to take notes will become a burden for Taichi (Toranosuke Kobayashi).

On the other hand, Taichi also wants to talk to Kohei about taking notes, but he is always completely blocked by Maya (Yuai Shiraishi) who is always looking for trouble, and he has not been able to have a good conversation so far.One day, when Taichi came home hungry after finishing his part-time job, Kohei came with a lunch.

One day during lunch break, Taichi (Kobayashi Toranosuke) learned that Kohei had begun preparing for the qualification exam. Masaki (Natsuo Taihu) and other friends of the same age were gradually beginning to think about the future. Taichi couldn't find the job he wanted to do.And a little uneasy...

At this moment, he bumped into a man Xi Qingshiro (played by Ryo Ikeda) carrying a large luggage on the side of the road.Among the luggage scattered on the floor were books about “Sign Language”.This encounter will greatly change Taichi's fate——!?

The freshman (Toranosuke Kobayashi) decided to work part-time at the sign language business company “sig-n” of Rhino (Ryo Ikeda). He was unfamiliar with computer operations and was conceptually incompatible with his boss Chiba (Shunsuke Daito).

Due to being too busy, Taichi was sleepy even during classes and meals. Hang Ping (Motoki Nakazawa) was worried about Taichi and had an ominous premonition in his heart.

One day, Taiyi suddenly asked Hangping: “What would you do if I said I didn’t want to go to college?”Kohei was stunned for a moment, but then he recalled his previous conversation with Shinya Sakuragami (Yuai Shiraishi)...

Taichi (Toranosuke Kobayashi) has made it clear what he wants to do and is determined to drop out of college, but he hasn't told Kohei (Motoki Nakazawa) yet.

On the other hand, Kohei asked Taichi: "What would you do if I said I wanted to drop out of school?"From that day on, I had a premonition that Taiyi might leave.After school, Taichi called Kohei out and finally told him that he would drop out of school.Kohei expressed his gratitude to Taichi who looked apologetic, and then...

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.
