Episode 5

**Former Couples Stay Overnight "You're Welcome"** (Moto Kappuru Wa O Tomari Suru `Dōitashimashite', 元カップルはお泊まりする「どういたしまして」) is the fifth episode of the My Stepmom's Daughter Is My Ex anime series.

## Summary

A brief flashback shows a young Mizuto and Yume before they were formally in a relationship with each other. It was a night that Mizuto cherishes a lot.

As he reads a book on the couch in their living room, Yume tells Mizuto to accompany her in buying a present for their mom for Mother's Day. Yume claims it'd be less awkward if they both gave it to her, and they could split the cost. Mizuto figures the latter reason is the true reason for her request and refuses as he wants to spend his Sunday in peace. Seemingly unfazed by the response, Yume accepts Mizuto's refusal and walks off only to return later all "dolled up", causing Mizuto to gawk at her, which breaks the rules they follow. Later, they ride on a subway train and get into an awkward position with each other because of the bumpy ride. They decide to stay in that position mainly because they'd end up in it again when the train gets bumpy once again. At the shopping mall, they visit an Isatan and look at the kitchenware for sale. Ultimately they decide to buy their mother a bouquet of carnations.

That afternoon, Yume catches Mizuto paying his respects to his mother's alter, and Yume comforts him. After this, they talk about how their parents barely spend time together despite being newlyweds. In Mizuto's opinion, he believes their parents are being considerate of them, and Yume comments that she doesn't think Mizuto was capable of noble consideration. They then contemplate a plan to get their parents closer by spending time together that's out of the house. However, this leads to nowhere, and the following day, they discuss it again during their breakfast. As it turns out, Mizuto found a place for them to stay, and it's at Kogure and Akatsuki's home. Mizuto also reveals that the two of them happen to be next-door neighbors.

On Saturday, the two visits the apartment complex Akatsuki and Kogure live at and are greeted by them. Once they separate, Akatsuki and Kogure tell Mizuto and Yume about their history with each other. Kogure also says a lewd thing directed at Irido, but said it as if it was a response to a comment made by Mizuto. Immediately, Yume starts banging on the wall and then sends a barrage of texts to Mizuto, calling him a pervert. In retaliation for what Kogure did, Mizuto hog ties Kogure in a sleeping bag and reads a poem that Kogure wrote about his feelings for Akatsuki when he dated her. This causes Akatsuki to slam the wall with her fists and be held back by Yume.

Afterward, they all eat at a restaurant called Saizeiya, and at first, Kogure and Akatsuki argue about what food they'll eat. Later, Yume and Mizuto get into a scuffle about what to drink and decide to mix their drinks with what's available at the soda fountain, following Kogure and Akatsuki's suggestion. This turns out to be a joke by the two, and Akatsuki then snuggles against Mizuto and asks him to tutor her, but he suggests that Yume do it as she's a better teacher than him. Although Yume believes that Mizuto was complimenting her, he then remarks that his little effort to get good grades makes him a lousy teacher, which upsets her.

Back at home, both sides study for the upcoming exams, and outside, Mizuto admires Yume's pajamas that Akatsuki forced her to wear. They then recall how similar their current interactions with each other are to when they first, and after that, they head to bed.
