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.

Mixed Feelings
Rom-coms have been dozens aplenty since the AniManga industry's early days, with most of the memorable classics (e.g. School Rumble, Ouran High School Host Club, Lovely★Complex to name a few) to modern-day juggernauts (e.g. Hataraku Maou-sama!, OreGairu, SaeKano, Date A Live, NiseKoi) making the scene yearly with no signs of the genre slowing down and becoming one of the most popular genres for just about any AniManga fan. Yet, for all of what the rom-com genre has to offer, there have been more bad nuts also appearing (Masamune-kun no Revenge, KanoKari) to fuel the fire for distastes. And most particularly for one mangaka by the ...

Sigh… Alright, where do we even begin with this one? First of all, if you actually finished all 24 episodes of this dumpster fire, like I did, I applaud your dedication, but sometimes I really do question the decisions I make, such as continuing to watch this week after week. Studious male harem protagonists have been somewhat of a repeating character archetype, like Futaro Uesugi from The Quintessential Quintuplets, or Nariyuki Yuiga, from We Never Learn. I am convinced however, that Umino Nagi is one of the worst harem protagonists that I have seen. He’s literally Kazuya, but gets good grades in school. He’s indecisive, ...
