Before I begin, I don't hate romance anime or romance in general so take this review with a pinch of salt.

Miki was living a relatively normal life until her parents announce that they are divorcing, this happens because they met another couple on holiday and they decided to switch partners. Obviously more than a little upset and not really warming up to the other couple's son Yuu, Miki now has to deal with this unusual situation, however as the series goes on Miki starts falling for Yuu but the romance web has only just begun as ex-girlfriends, long time friends and even other couples get drawn into this large scale romance fest.
If the premise is anything to go by this will feel complete bullshit but if you watch soap operas this will be the closest anime to one along with other such titles as Ai Yori Aoshi, Maison Ikkoku and Kimagure Orange Road which sadly means it's very dated, very much 90s aesthetic.
It's not a bad series per say, the writing is at least solid and the romances are threaded together well even if it feels like a rollercoaster at times, honestly the only really terrible thing about this show is that the series had to start on such a bullshit premise, even as an adult and at the age where this sort of thing is not uncommon, I find the parent's nonchalant attitude to all this rather jarring.
Early dubbing is fine and non offensive, nothing special.
Final Verdict: A carefully woven romance story that needed such a bullshit premise just to start, it's fine if you like soap operas but alot of the modern romance anime like Toradora and Nisekoi are much better with the genre.
