My Stepmom's Daughter Is My Ex

While they were in middle school Mizuto and Yume were boyfriend and girlfriend but shortly before they started at high school they decided to break up. A mere fortnight later they are thrown back together when his father and her mother get married to each other! They decide that they will try to act like siblings and avoid any romance despite now living under the same roof. As they are the same age they argue over who should be considered the elder so they make a bet; the first to show signs of being attracted to the other is to be considered the younger.

This could easily have been another fan service led ecchi series but it manages to stay fairly innocent. The story progresses nicely; thanks to their wager we get plenty of amusing situations. The character designs are solid as is the animation. Overall I'd certainly recommend this to those wanting a fairly chaste story of possible romance.

These comments are based on watching the series in Japanese with English subtitles.
