16-year-old super-studier Nagi Umino, second-year student at the Megurogawa Academy high school, was switched at birth. On his way to a dinner to meet his birth parents, he accidentally meets the brash, outspoken, Erika Amano, who is determined to make Nagi her fake boyfriend as she never wants to actually marry. But once Nagi makes it to dinner, he finds his parents have decided to resolve the hospital switch by conveniently having him marry the daughter his birth parents raised...who turns out to be none other than Erika herself!
You're going to be my boyfriend.
I'm not going to marry you.
You aren't going to beat me!!!!
Would you please go out with me...?
Can we do our morning study sessions together...?
I thought you live by yourself.
Is my fate going to change?
Are you going to marry him?
The Kuroshio currents beckon to me.
Don't treat me like your kid sister.
I can't forget that just happened.
It's not that I like you, yet.
Things aren't quite working out, are they?
Walls exist to be overcome!!
We have to tell her... about our secret!
I want to talk about now.
Anything could happen right now!
Who is that person?
You must have noticed by now.
I want to grow up already!
It's a secret between you and me.
I'll Be There With You
What Should We Do Now?
All That Matters Is That You Two Are Happy
