In this episode, everything revolves around Minato and his close friendship with Uta, a girl from his class. Their affection becomes evident as they plan to build a door made of leaves for their secret fort. However, their childish innocence is disrupted when a boy from another class approaches Uta, and the children speculate about his intentions.

The boy, whose name the children don’t immediately recall, asks Uta if she would like to go out with him, and to the surprise of her friends, she agrees. Minato and his friends are shocked that Uta suddenly enters a relationship, and Minato in particular seems unsettled by the changed dynamic.

The children’s naivety is also reflected in their inability to understand that Uta is now someone else’s girlfriend.

The group decides to help Uta prepare for her date by suggesting she dress up. They face a dilemma, as they only have a limited selection of clothes and their financial means are restricted. Minato, who is desperate to help, asks her older brother Hayato for fashion advice, leading to a humorous misunderstanding about Hayato’s taste.

On the day of the date, Minato’s protective instincts kick in. He plans to sabotage Uta’s date because he can’t accept the change in their relationship. His brothers, Mikoto and Gakuto, watch the events unfold with a mix of amusement and concern.

The episode takes a deeper turn when Minato’s friend Nikaido shares his own experiences with jealousy and relationships, offering insight into the complexities of growing up. Minato reflects on the inevitability of change and the nature of friendships between boys and girls.

The episode ends on a cliffhanger: Minato considers the radical idea of asking Uta out himself to stay close to her.
