After more than ten hours of flying, Zhu Zi and a few girls finally arrived at their destination.

Here, Zhu Zi also rented a luxurious apartment.

The girls had been on the plane for a day, and they were all very tired, but after seeing this apartment, their eyes were bright and bright.

"There are three floors in this apartment, the first floor is the living room, kitchen, entertainment room and so on, and the second floor is some of the rooms for living. In teams of two, go up and pick your favorite room. Zhu Zi waved his hand, and the girls dispersed.

It didn't take long for the members to return to the area.

"Teacher Zhu Zi, you are simply too tyrant. Rina Ikoma sighed.

"That's it, let's be friends, Mr. Tuhao. Ikuta echoed.

Zhu Zi rolled her eyes: "You girls, I guess what kind of pit will be dug for me." But do you think I'm going to be the kind of person who can be fooled?"

"Teacher Zhu Zi, you misunderstood. The respect we have for you is from the bottom of our hearts. "Yona Kojima has a charming face.

Zhu Zi lifted Erlang's legs and lay comfortably on the sofa.

"Cut, you girls, you want to pour me confused soup. It's still early. Today, everyone has been traveling for a day, and the time is not early. Let's all go back and rest. I wish you all a good night. Zhu Zi said with a smile.

"Yes, Teacher Zhu Zi. The members were indeed a little tired, and they did not refuse Zhu Zi's kindness.

After walking around the apartment for a while, everyone went to sleep.

At the same time, AKB48's new single was released. The central member of this single has changed dramatically.

This single is a new work released about three and a half months after the release of AKB48's previous single "Hopeless Unlimited", and there is also an album sandwiched between the release dates of the two singles, the sixth album "This is Rhodes, Let's Jump Here!", which was released on January 21, 2015.

The members of the singles selection team who will sing the new song were announced during the encore time of the last day of AKB48 Request Hour Setlist Best 1035, an annual concert event held at the Tokyo Dome City Performance Hall on January 25, 2015, and the new song was performed live for the first time. Later, on February 28, AKB48 was invited to participate in TV Asahi's live music program "Music Station", where they performed their new songs for the first time.

Like all AKB48 Group's related discography, this single is also released in multiple versions of one single. However, unlike most AKB48 albums, which use the names of each team as the record version of the single, this single adopts a similar approach to the 34th single "If You Were in the Sycamore Tree or something", using the name of the sister group as the version name, and released five versions with different included tracks: Type A (AKB48's A), Type S (SKE48's S), Type N (NMB48's N), Type H (HKT48's H) and theatrical version. In addition to the theatrical version, the other four main releases also have a limited edition that was only sold in the early days of the single's release, and a regular version that is sold normally, with different bonus items and cover designs, so the single actually has a total of nine different sales versions.

In the third track of each major release, a new song sung by the sister group is included as the B-side song, namely AKB48's new song "Summer When Spring is Approaching" from Type A, SKE48's new song "If the World Is Crying" from Type S, NMB48's new song "Punk Rock" from Type N, and HKT48's new song "Big Train" from Type H. The inclusion of sister group songs in AKB48's singles was originally the convention of "Guess Fist Singles", which used guessing to determine the list of single selection group members from the 29th single "Forever Pressure", but since 2014, the release of the guessing single has been cancelled and replaced by the solo single of the champion of the guessing tournament (that is, the first solo single "Give Me a Kiss Instead of Being Gentle" by NMB48 member Miyuki Watanabe) was changed to "Green Flash" Various versions of this single include songs sung by sister groups.

On February 16, 2015, it reached No. 1 on the Oricon Weekly Chart on its first day, making it the 26th single album to win the weekly chart after "RIVER". This work broke Ayumi Hamasaki's record of 25 consecutive singles No. 1 on the weekly chart, and AKB48 has had weekly singles for 7 consecutive years (2009 to 2015), and it has also updated the "Good Morning Girl Group". "The previous women's group record (for 6 consecutive years). It sold about 1,001,000 copies in the first week, and it was the 20th consecutive single album after "Turning into a Cherry Blossom Tree" and the 21st in total to sell one million copies.

As mentioned above, "Green Flash" has released a total of five versions of Type A, Type S, Type N, Type H and the theatrical version with different song content and nine different cover designs, among which the main versions such as Type A, S, N, and H also come with a DVD containing the MV of the new song in addition to the music CD, and only the theatrical version is pure music and no free film.

In response to the lyrics and theme of the MV for the main A-side song "Green Flash", photos of the 16 singles members were placed on the covers of the four main versions with the same makeup and tearful expressions. The cover of each edition features four members, with the first limited edition photo of the members being photographed with their eyes closed, while the regular edition is photographed with their eyes open.

In terms of the tracks included in each version of the record, in addition to the main A-side song "Green Flash", each version includes two other B-side songs. Of the five versions, only the Type N and theatrical versions included the same B-side song, "A Tale of Shoes and an Umbrella", so the entire single and all versions of the song included a total of nine B-side songs. Among the nine B-side songs, only the song "The Stamens of First Love", which is only included in the theatrical version, did not shoot the corresponding MV.

Type A is a version of the B-side song "Summer When Spring is Approaching" sung by AKB48 Audition, which is composed entirely of AKB48 members. In addition, this version also includes the opening song "Fight" of the TV series "Maryu Suga Gakuen 4" starring AKB48, and the MV of the two songs is also included in the accompanying DVD. In terms of cover design, the front and back covers of Type A include photos of the two center Yuki Kashiwagi and Yona Kojima, the two centers of the single, and a total of four members of the single, Juna Matsui and Sakura Miyawaki.
