Synopsis

Yuuta Asamura gets a new stepsister after his father remarries, Saki Ayase, who happens to be the number one beauty of the school year. They promise each other not to be too close, not to be too opposing, and to simply keep a vague and comfortable distance, having learned important values about men and women relationships from their parents' previous ones.

Saki, who has worked alone for the sake of her family, doesn't know how to properly rely on others, whereas Yuuta is unsure of how to truly treat her. Standing on fairly equal ground, these two gradually learn the comfort of living together.

Their relationship progresses from strangers to friends as the days pass. This is a story that may one day lead to love.

There’s so much to praise about this anime. It truly gives the feeling that the characters are real people, with complex thoughts and emotions, reflecting on the consequences of their feelings. This makes the story highly immersive and engaging, allowing the viewer to connect deeply with everything the characters experience.

The background music is wonderful and perfectly complements each scene, enhancing the emotions without ever overshadowing the story. The voice acting is also very well done, giving personality and authenticity to the characters, which further strengthens the immersion.

The anime’s visual style is pleasant and harmonious, with colors and designs that make every scene beautiful to watch. ...

Mixed Feelings
I give this anime a 4 because both of the main characters are perfect squares. Another review on here says that this show is about about two robots discovering human emotions and that user could not be more spot on.

I think some people will enjoy what this show has to say, but the two main characters have such little chemistry that the moral dilemma of their relationship does not even matter. This show is more interested in talking about step sibling relationships (a topic that might apply to a handful of people in real life) than it is in portraying one. These characters would ...

Bland. Boring. Monotonous. I'd say this sums up this show pretty well.

Such an uninspired "romance" show that felt like it was trying to hard to be different. I won't lie tho, it was different. But different in that it was more boring and dull than the other stepsister shows out there. Maybe that deserves it's own award.

First order of business: Story. Stale and Tiresome. I felt about 90% of this show was a back and forth between the characters with no progress and stagnant situations and dialogue. Also chemistry. THERE WAS NONE. Goodness, I felt absolutely nothing between the characters AT ALL. They ...
