|1||October 26, 2018|| The IZONE members are preparing for living together and packing their things while saying good bye to their families. They are having a meeting with staff about the future plans, which includes them having their first variety show (IZ*ONE CHU). They show bits of their very first commercial photo shoot before even debuting.
When the girls move in together, they live in two building. Kim Chaewon, Ahn Yujin, Choi Yena, Kang Hyewon, Kwon Eunbi and Kim Minju live together in one building and Jang Wonyoung, Jo Yuril Honda Hitomi, Miyawaki Sakura, Lee Chaeyeon and Yabuki Nako live together in the other building and their life together is shown. Then they have their album cover shoot for their upcoming debut COLOR*IZ as well as the recording of the songs. The main part of the episode is about the M.T. (Membership Training), where they go on a trip. You can see them travelling by bus to an unknown location where they play games in order to see who will have to buy food. When they arrive in Tochigi, Hitomi's home town, they go shopping in the mall and even run into Hitomi's old friends. At the end of the episode, the first teaser trailer for La Vie en Rose is shown.
|2||November 2, 2018|| Still in Tochigi, the IZ*ONE members visit Hitomi's family for her 17th birthday, where they meet her father, mother, brother and sister. The girls also read heartfelt letters to Hitomi's mother to ensure her that she is in safe hands while in Korea. More preparation footage for the music video for La Vie en Rose is shown.
They eventually decide on a leader. Up until this point, Eunbi had acted as the temporary leader and it was unanimous among the members that she would become the official leader, but they decide to prank her and Sakura suggests Chaeyeon as the leader because her Japanese is the best out of the Korean members and it would be difficult for herself, Nako and Hitomi to understand if it was Eunbi who gave the instructions. When the anonymous voting for the leader is revealed, Eunbi was the only one who actually voted for Chaeyeon and Eunbi starts crying because she's so happy that everyone chose her as their leader. Some behind the scenes footage for the upcoming debut showcase are shown again towards the end as well as the first performance of La Vie en Rose and the members see that their debut has peaked at #1 on the charts.
|3||November 8, 2018|| While Yena and Wonyoung do their makeup and pretend to be beauty gurus, Sakura, Chaeyeon and Chaewon prepare boxed lunches for their picnic that day. Sakura finds out that Koreans do not seem to like pickled apricot because of its sour taste, and they decide to make onigiri with various flavours and prank some members with the sour apricot onigiri. On the picnic, Eunbi, Yuri and Yena fall victim to their prank and they don't enjoy the onigiri at all.
After that experience, they have delicious sandwiches and then decide to play games in two teams: Hitomi, Hyewon, Wonyoung, Nako, Yujin and Chaeyeon on Team A and Sakura, Yena, Eunbi, Chaewon, Yuri and Minju on Team B. For the first game, they have to fold a mat as small as possible while still fitting all team members on the mat (Winner: Team A). For the second game, each member hides a treasure in the park and the team that finds the most treasures wins (Winner: Team B with 6 treasures, of which 3 were found by Sakura alone, versus 2 treasures found by Team A). For the third game, they have to throw a show on a mat. After Hitomi is the only one that manages to land her shoe on the mat, Team A wins the game and therefore Team B has to carry out the penalty of tidying up the picnic and carrying everything back to the van. In the second half of the episodes, the members decide to visit their old trainers from Produce 48 and make some food for them to show their gratefulness.

In the evening they come home surprised to see that the house has been cleaned and find personalised T-shirts with a motif drawn by Sakura and a letter on their beds.

At the end of the episode, they go to school, where they do some maths work, then explore the classroom. Lastly, there will also be one mystery friend for the whole group.

Nako, Wonyoung and Eunbi ask a fortune teller to help them figure out who their secret friend is. Nako believes Wonyoung is her secret friend who, again, only tells the camera that it's true.
Later, they go back to school late at night. Each one of them has to find a key to their locker hidden somewhere in the school, which has been turned into a haunted house. When they all find their keys, Sakura is the only one with 2 gifts in her locker and some cake, and everyone believes Eunbi to be Sakura's secret friend. In the end, they celebrate Sakura's birthday.

Sakura says in Japan, it is common to eat yukhoe (raw beef with egg) in Japan, but they realise she's kidding because she's been talking about eating yukhoe all day. Hitomi tells them it's common to eat sukiyaki (expensive grilled beef). They discuss what to have to eat, but then they ask Yujin, who suggests Chinese food and in the end, they go to eat Chinese food anyway. It is revealed that Chaewon is Yujin's secret friend.

|4||April 11, 2019||The girls are led, in blindfolds, to a secret location, where they are then told they will be holding a guerilla concert the same evening. Before that, they have to go out and promote the concert, though, so they split up in teams of 4. Wonyoung, Hitomi, Yena and Chaeyeon are in charge of the western part, such as a university in the west and Gangnam. Minju, Yuri, Eunbi and Hyewon do the same at a university in the eastern part of the city. Sakura, Nako, Yujin and Chaewon go on a city center tour bus and go to populated places in the city to promote. The girls' goal was to get 1,000 people to come to the guerilla concert, with their realistic expectation set at 300 people. When coming on stage, the girls wore blindfolds again and the crowd was instructed to stay silent so they wouldn't know how many people came. When they removed their blindfolds, they found out that over 2,000 people came. Then there are clips from the concert shown where they perform La Vie en Rose, Up and Violeta.|
