A Couple of Cuckoos

 Okay, so this is a rom-com with a strange premises...

Superstudent Nagi Umino was apparently switched at birth... and from there on we get a very special plot.  So this might be good fun!

Because on his way to dinner with his birth parents, he runs into brash Erika Amano, who wants to make him her fake boyfriend.  But arriving at the dinner, he learns his parents want to make up for the switch by having him married off to the girl they raised instead... which turns out to be Erika!

He has a crush however on his classmate Hiro, who is the only student smarter then him, and when he finally overcomes her in the test scores, she finally acknowledges him.  But not in a way he would have liked... but just as he makes some progress, Erica transfers into his class.  And instantly bonds with Hiro...

 

But Nagi has a crush on Hiro that hard, he even starts dreaming of school assignments as dates. But during a field trip, Erica is on the point of confessing she has a crush for Nagi herself.  Sachi, Erica's younger sister, comes over to visit but decides to move in with them instead.  Nagi confesses to Erica he isn`t ready yet, but he unwinds a bit after a fishing trip with his dad.  And gets to know the younger sister better as they go shopping together to find a suitable mother's day gift.  When he bumps into her during a black out, Sachi realises she has serious feelings for her older brother.

But it all reflects on his academic results, and when he doesn`t come up on top but only 13th, he gets an emotional beatdown.  But as he recovers, Erica asks him for tutoring in earnest, as she would be forced back home if she fails the exam.  But the festival is in town, and they all go there, Nagi hoping to get a date with Hiro there.  But he takes Erica on the date instead.  But when they run into Hiro, she finally asks how they are related, but Erica drags Nagi away to avoid the answer.  She catches up and they tell the story, Hiro understanding and approaching Nagi to no longer hold secrets for her.

During a trip with another classmate who has the hots for Erica, Hiro tells Nagi he is happy to be there with him, while their classmate confesses (sort off) to Erica he likes her a lot.  Later on, Erica decides to finally tell Nagi the truth, showing him an old family picture, and how he has an older brother.  While trying to find him, or even figure out he has one, he goes on a cycling date with Hiro.

But when the results of the schoolyear come in, he managed to actually rank first and finally "defeating" Hiro as such, winning his date with her.  But first, the gang goes to the beachside to celebrate the end of the schoolyear.  During a stay at a vacation home, the girls find out from each other they all actually like Nagi a lot, while Erica keeps trying to remember things about her missing brother.

Nagi and Hiro end up in an onsen hotel, but it turns out there is only a double futon in their room.  Instigated by Hiro, they are about to give in to the spark between them.  But Erika and Sachi barge into the room at a completely wrong moment, and a serious wrong impression followed by some claps to his cheecks ensue.  During Nagi's father birthday, an old family album is taken out of the closet.  They learn some facts about them as a result.

It wasn`t a bad series at all, though it felt somethings where left unresolved at the end.  But for a weekly anime watch, it was okay.
