Nagi Umino and Erika Amano, a studious high school student and a social media star, had nothing that linked them together—until they found out they were swapped at birth. When the sudden news is revealed to both of their families, their parents quickly devise a proposition with neither Nagi's nor Erika's knowledge: in order to restore them both to their rightful families and ensure everyone's happiness, the two should get engaged.

When informed of this, Nagi and Erika are quick to reject the absurd plan, refusing to go along with their parents' wishes. But, with neither party willing to back down, only time can tell where their relationship will go.

Its just an example.) It started pretty good. I was hyped because I thought that the plot is actually pretty deep so It cant be just a "normal" romcom. Well, It is. Through the whole series I thought, "Why do they take this so lightly? They were swapped at birth and meet their real parents after 16 years so why?" I thought that this anime would be a bit more ...

I guess I had high expectations for this anime and should have figured it out right away by looking at the ratings. The premise looked interesting, so why not give it a chance. Long story short, 24 episodes gone and we're still where we were.

I like watching the development of the characters, the evolution of their relationships, and I like rooting for the main characters. The MC is always a slow burn. He's presented as the "second" smartest in the school, but his expressive skills and emotional maturity are at an all time low.

I didn't like FMC perhaps one bit. Erika as the spoiled little ...
