When athletic new arrival Saku claims school is just boring, Tatsuki uses collage art to help him open up — and spots clues to a deeper issue.

With summer vacation around the corner, Tatsuki plans an overnight camp. Meanwhile, reclusive sixth-grader Nene announces she's quitting Yukanai.

Faced with the raging Nene, Tatsuki feels powerless to do anything. He recalls the struggles his son Sora faced in junior high.

Shizuku notices a student has been absent for months. Tatsuki jumps into an online game to reach him — but the isolated boy isn't ready to let anyone in.

After Tatsuki is hospitalized saving Tomoki, Shizuku pushes herself to the limit to reach the troubled teen. But who's looking after her?

After Umine calls Tatsuki "Papa" and a fight breaks out, Mikumo suggests button art to understand her feelings. The results reveal a telling contrast.

Mikumo suggests Tatsuki paint a childhood memory, but flashbacks overwhelm him. A visit to his family home uncovers a painting tied to his father.

As Sora's behavior grows violent, Tatsuki and Yu reunite to share memories through family photos and mementos — hoping to find a way forward.

After Sora lashes out at him, Tatsuki comes up with an idea for an activity at the upcoming music festival, hoping it will help the teen finally open up.
