**"Youthful Indiscretion"** (Wakage no Itari, 若気の至り) is the ninth episode of My Stepmom's Daughter Is My Ex anime series.

## Summary

After officially starting their relationship with each other, a young Mizuto and Yume kiss. Eventually, Mizuto invites Yume to his house and brings her to his room. Under the intention that they were going to sleep together, Yume was nervous, as was Mizuto; however, his motives weren't what Yume expected. Mizuto wanted to read a book with Yume that she was interested in, and when they finished it, Mizuto walked her home. The two of them would lament over not sleeping together, despite being psyched up for it.

On the day of their first day of school as third-year students, they walk together and hope that they end up in the same class together. However, Mizuto ends up in Class 3-1, while Yume ends up in Class 3-3. On April 5th, around dusk, Mizuto and Yume study in the library, and Yume laments how it's not the same without him in class. Lamenting how she's alone in class, Mizuto promises to hang out with her after school and during the holidays. Fast forward to the ninth, Yume excitedly informs Mizuto that she has made a new friend with similar interests in her class. She would then read a book suggested by the friend and talk about it to Mizuto as they walked home. Although a positive thing, Yume's new friend would intervene with Mizuto, spending time would her, causing him to feel discouraged. Mizuto would eventually not meet up with Yume in the library, and when Yume catches up with him to apologize for her tardiness because of her friend. As they walk home together, Yume starts to talk about how she mentioned him to her friend, but Mizuto coldly declares that he has no interest in hearing about her friend. At his home, Mizuto would regret acting coldly toward Yume about her friend.

The following day, Yume could cancel her plans with her friends to spend time with Mizuto; however, when Yume arrives at the library, she finds him talking to another girl. When they stopped talking, Yume approached Mizuto, who apologized for his behavior in the past, noting his desire to keep her all to himself. In turn, Yume calls out Mizuto for his hypocrisy and the fact that he talked with another girl who sat in "her seat". Although Mizuto tries to explain that the girl was looking for a suggestion on a book, Yume takes it personally, escalating into an argument between them. At her home, Yume reflects on how betrayed she felt by Mizuto's actions and vice-versa with Mizuto, who still regrets how he acted toward Yume the day she acted considerate toward him.

Eventually, Yume and Mizuto would bump into each other at a bookstore. They happened to want the same book, but Mizuto gave Yume the last copy in the store for her to enjoy. Afterward, they would eat at a restaurant, where Mizuto would formally apologize to Yume, and she accepted.

Around August, Yume tried to invite Mizuto to the festival that month but backed out at the last minute, and when she went to attend it, she reflected on the puppy love she had for him. On August 28th, the day of their one-year anniversary, Yume notes how Mizuto didn't message her about it. The rift between them would continue to grow, and because they were never in contact with each other from Christmas through Valentine's day, they both decide to break-up at the graduation day of their middle school. Not long after this break-up, the two of them would learn that their parents were getting married, and they would become step-siblings.

In the present, Yume claims she's borrowing a book that was the same book they first read together in his room. This would lead to a contentious argument between them.
