This drama is adapted from the manga of the same name, telling the story of Gojo Shinna (Kouta Nomura).) is a high school student who is very interested in making traditional Japanese Hina dolls and aspires to become a “tōshi”.However, because his interests are different from those of his peers, Xinai feels lonely in school and alienated from other classmates.

Kitagawa Umume (Riko Nagase)) is a popular figure in school. She looks glamorous, but in fact she is an obsessed cosplay enthusiast.When Hai Meng discovered Xinai's excellent ability in making puppet costumes, she asked him to help make cosplay costumes.As the cooperation between the two gradually deepens, their relationship is also quietly changing...

Gojo Arina (Kouta Nomura) aims to become a doll maker, but because he is too focused on dolls, he has different interests from his peers and cannot integrate into the class.One day, the sewing machine at home broke down and she couldn't make clothes for the doll. She thought of going to the school's costume room to borrow a sewing machine.

In the empty clothing room in the morning, Aina is making clothes, and the class star Kitagawa Ummu (Nagase Riko) appears.Hai Meng is a lively hot girl who lives in a different world from Xin Cai.Seeing Xincai making clothes, Haimeng teased him, and Xincai was so surprised that he dropped the doll to the ground.

Because of the psychological trauma caused by past experiences, Xincai hurriedly hid the doll, but Haimeng's reaction was beyond Xincai's expectation. She praised the doll after seeing it.

Suddenly, Haimeng said to Shina: “I want Gojo-kun, who can sew, to see this thing”, and then Haimeng started to take off his clothes——

Umume (Riko Nagase) commissions Arina (Kouta Nomura) to make her cosplay costume.Xin Cai could not believe that he would interact with Hai Meng who lived in a different world. However, Hai Meng suddenly visited Xin Cai's home and told him that he could not wait to investigate everything about Xin Cai.Xincai successfully completed the costume design while being surprised by Hai Meng's mobility.

Faced with Haimeng, who talked to him directly even on his days off, regardless of the surrounding eyes, Xincai began to keep a distance.However, Hai Meng expressed to Xinai that he didn't understand why he wanted to avoid him even though he was a friend.

Xincai couldn't hide her joy at having her first friend and decided to work hard to make clothes for Hai Meng.At the same time, Xincai also expressed his intention to become her stylist to Hai Meng, and gradually opened his heart to Hai Meng.During this interaction, Xincai learned that Hai Meng planned to participate in the cosplay event, but there were only two weeks left before the event started...

Arata (Kouta Nomura) knew that she had to complete the costume within 2 weeks before the event started, and was anxious because she didn't have time.Umume (played by Nagase Riko) is very much looking forward to such new dishes.Hai Meng showed Xin Cai pictures of cosplayers as a reference for costume production, but Xin Cai's reaction was colder than Hai Meng expected.Feeling uneasy, Haimeng asked Shinna about the reason.There are new dish ideas out there—.

One day, Xinai's grandfather Kaoru (played by Yamada Akigo) suffered from back pain.At the same time, the mid-term exam period has also entered. Taking care of Xun, studying for exams and making clothes, Xincai is gradually forced into a desperate situation.I couldn't practice the first division every day, and I was disappointed with myself for giving up halfway.Although my heart was almost broken, I just wanted to see Haimeng’s happy expression, so I cheered up and tried my best to make costumes before the event started——.

Arina (Kouta Nomura), who has successfully completed the cosplay costume, sadly realizes that the time spent with Umimu (Riko Nagase) is coming to an end.Hai Meng, on the other hand, asked Xinai nonchalantly, what should he do for his next cosplay costume?Xincai, who thought it was only the last time, was surprised by Hai Meng's inquiry and was happy to be able to work with Hai Meng in the future.

On the other hand, with the cosplay event day as the boundary, Haimeng's attitude towards new dishes also began to change subtly——.

One day, Miesa Touha, nicknamed Zhu Zhu (Ikeda Juna), suddenly came to Shinna's house.Sajuye said that after seeing the cosplay photos of Haimeng at the event, she wanted to commission Shinka to make costumes.After get off work, Hai Meng also joined them. Faced with Zhu Zhu, whom she admired, Hai Meng was very excited and agreed to take a cosplay photoshoot together.Driven by Haimeng, Xincai also decided to make clothes for Sajuye——.

One day, the school sent students application forms for further studies.Shina (Kouta Nomura) and Ummu (Riko Nagase) discussed the issue of a way out, but after some discussion, they still filled out “Uncertain”.

Haimeng, Xincai, Sashouye, and Xinshou went to the ruins for a field trip.There Shinna heard Sajuha's (Juna Ikeda) idea about cosplay.

A few days later, Uimeng, who was working as a costume maker at Shinna's house, told Shinna that Sajuha's sister Shinju (Toshima Shinsakura) actually wanted to play cosplay.Xinaica is afraid of telling others what she likes, and resonates with Xinshou's desire to hide his “like”.However, Haimeng said that you would be happier if you were honest about the things you like%. What did Xin Cai think of when he heard this sentence——.

On the day of the cosplay event, Haimeng and Sashouye arrived early, but Xinshou was late.

Entering the summer vacation, Shina (Kouta Nomura) and Umume (Riko Nagase) separated.Xin Cai focused on his spiritual practice single-mindedly.Hai Meng is also working hard so as not to disturb Xin Cai.Hai Meng's favorable impression of Xin Cai is getting higher and higher, but Xin Cai seems to have no idea what Hai Meng is thinking.Instead, he struggled with his spiritual practice and got into trouble mentally.In order to let Xin Cai relax, Hai Meng invited him to go shopping.While shopping, Xincai decided to start making “Rizkyun”'s cosplay costumes that Haimeng liked again.The clothing fitting will be held at Hai Meng's home.

Xin Cai came to Hai Meng's home for the first time and was extremely nervous.Trying on the clothes got the two of them in high spirits, so they decided to hold a photo session on the side.In order to take good photos, the two indulged in it and unknowingly had close contact in bed - at this moment, Hai Meng's father suddenly came home...

Although Umume (Riko Nagase)'s father solved the misunderstanding about her, she was prohibited from participating in cosplay until her summer vacation homework was completed.As a result, the opportunities for Shincai (Kouta Nomura) to meet Haimeng become few and far between.Uimeng confided his love troubles to Sajuha (Juna Ikeda) and Shinshou (Toshima Shinsakura), and with their encouragement, he decided to officially confess to Shina.After accepting these suggestions, Haimeng decided to confess his love to Xincai after the summer vacation.

After the summer vacation, Hai Meng and Xinai started to make new cosplay costumes.At this time, they were seen by their third-grade male classmate Amano (Shiotaichi), and Shina's work on making cosplay costumes was about to be exposed.Amano stepped forward to chat, and Shinna was asked about role-playing related matters. He hesitated and fled the scene.

During this period, Hai Meng and Xincai went to participate in a cosplay event on the weekend.However, there they are surprised to see Amano appear as well - and he's dressed in women's clothing.
