This is a story of two couples who switch partners after university. And then, 18 years later, they switch partners again, divorcing and remarrying immediately. And then, on top of that, they all move into one big house together, the four of them and their two teenage kids, Miki, the main heroine, and Yuu, the Marmalade Boy. The teens start off on the wrong foot but after some time, they become good friends and then they fall in love. But then the real bombshell comes when it seems that Miki and Yuu are actually half-siblings, that they're blood related. But are they really?

Sakurai Hinako as Miki and Yoshizawa Ryo as Yuu were absolutely fabulous! I loved how different they were, Miki and Yuu. Miki was so brash, always saying out loud what she didn't like and not budging. Yuu, on the other hand, kept it all in, all his hurt and everything else, because all he wanted was for their parents to be happy - despite their questionable life choices! - for everyone to be happy.

It's a story about the consequences of miscommunication, really. Because Miki and Yuu were simply trying to navigate the mess that their parents unwittingly created by keeping vital info from them. What I did love, though, was that not for a single moment did the kids think that they were not loved. They knew they were, deeply. Even Yuu, thinking that his dad was not his real father, didn't feel bitterness towards his parents, no, he was grateful that his mom didn't simply abort him and that his dad brought him up as his own child and he loved them for it. It was honestly wonderful.

I loved it a lot. What a weird and not at all normal family, true, but also so full of love!
