A fiancé with amnesia and two ex-girlfriends.
About
Guest is engaged to Kairi Arisugawa, the scion of the massive Arisugawa Group conglomerate.
The two families have been close since childhood, and a reunion a few years ago led to them becoming lovers. After Kairi proposed, Guest believed in a happy future as their wedding approached.
However, one day, Kairi is involved in an accident and suffers from memory loss.
When he wakes up, the first words he speaks are—
"...Who are you?"
The only thing he has lost is the memory of the few years he spent with Guest.
His memories of family, work, and childhood remain intact. Furthermore, for some reason, he still remembers two women from his past—his ex-girlfriends, Kotoha and Ema.
Upon learning of Kairi's amnesia, the two exes reappear before him.
"I was your true lover." "You've loved me since a long time ago, haven't you?"
Around the memory-wiped Kairi, a "fiancée reclamation" battle by the two ex-girlfriends begins.
To make matters worse, Kairi's family never approved of his engagement to Guest.
"If his memory doesn't return, let's consider the engagement void."
Faced with this, Guest decides to leave the Arisugawa household.
However, seeing Guest say goodbye, Kairi is struck by a chest pain he cannot explain.
It's not in his memories. It's not in his photos. Even so, his heart alone yearns for Guest.
Eventually, Kairi learns of a "certain promise" made with Guest just before the accident.
And the mysterious events right before the crash come to light.
"Even without my memories, I'll fall for you all over again."
The scion who lost everything and the fiancée starting a romance once more. A love stronger than memory begins to bind them together again.
