My Ex Needs Taking Care Of

Episode 2

After entering high school, Yume was making an effort to change her personality and looks in an attempt to reinvent herself as a model student. It was all so far so good, but there was one thing she couldn't change about herself. She was never very athletic. On the day of the physical fitness test and body measurement check at school, a melancholy Yume is approached by Minami Akatsuki, a girl from the same class. Meanwhile, Mizuto is as disinterested as ever...

Episode 3

It's nighttime at the Irido residence. Yume has somehow found herself with Mizuto's boxers in her possession. If Mizuto were to find out, it would almost certainly mean she would have to face the punishment of admitting to being the younger sibling. Hoping to avoid this outcome, Yume waits for Mizuto to fall asleep before heading to the bathroom to return his underwear to the laundry basket. But who does she pass in the hallway, but a bewildered Mizuto, mouth agape, with Yume's very own bra dangling from his grasp.

And how else to do it but to show her that Yume only has eyes for Mizuto?

Ah, high school. Is there any better place to start fresh after a horrible middle school relationship? Nope! Not unless your ex ends up at the same school as you and is now your stepsibling. What was supposed to be a sanctuary of peace where I could avoid ever seeing her again has become a living nightmare! Everywhere I look, I see her—in my house, in my school, in my class. There's no escape! She even claims that she's the older sibling. Like hell she is! But I won't lose to her. After all, I'm the older brother in this new family situation. That's right, we're family now. No matter how much we may have thought we loved each other before, we saw one another's true colors and realized we weren't meant for each other. That's why even though we may keep up a buddy-buddy sibling act for the sake of our parents, things will never go back to the way they used to be.
