Listless geek Mizuto Irido and introverted nerd Yume Ayai seemed like a match made in heaven, connected by their mutual love for literature. Unfortunately, their differences gradually grew, and they separated just after their middle school graduation. But, as if by divine comedy, the two find themselves reunited as step-siblings.

A rivalry begins to brew between the former couple, both unwilling to acknowledge the other as the older sibling. In an attempt to "solve" this issue, Mizuto and Yume agree upon a rule: whoever crosses the boundaries of siblinghood norms loses, and the winner will not only be called the older sibling, but also get to make a request. However, now that they live under the same roof, the lingering memories they share start to influence their actions—possibly rekindling the feelings that may not have been fully extinguished in the first place.

"To me, you felt more real than anyone I'd ever met."

Looking back, I can only describe it as youthful indiscretion, but from summer of 2022, I watched what you may call a beautiful anime, with a simple but engaging plot, realistic characters and interactions, and a touching story. With confidence, I can say that "My Stepmom's Daughter is My Ex", also known as Tsurekano, was an anime I enjoyed from start to finish, an anime that never felt like a chore to watch, and most importantly, an anime that connected to me.

Now look, I get why many people dislike this anime. I'm not here ...

Mixed Feelings
This show can be summarized as follows: Ex-lovers obsessed with one another who later became siblings and are still obsessed and in love with one another in the present. The show is either a hit or a miss for most people, as there is no middle ground. Watch the first three episodes and decide whether it is worth continuing to watch. Even from just watching the trailer, you'd already know what to expect from the show, including the art and sound quality.

Yume and Irido's chemistry isn't all that great to begin with, and from a logical standpoint, their relationship appears forced with little to no ...

Watching My Stepmom's Daughter is My Ex reminds me of the time when I was forced to stay for detention because I made a mistake in class. The real question to ask is if My Stepmom's Daughter is My Ex is a mistake. Yes, it damn right it is.

Based on the novels of the same name, you don't need a vivid imagination to see how our two main characters used to have a history together. It's simple as it gets: they used to be a couple. As fate would have it, Mizuto and Yume would reunite again due to their parents' martial status. The show ...
