Story

Iori, who was corresponding with her late great-aunt's former lover.

One day, a high-spec man appeared, as if he had crossed over from the Showa era to Reiwa!?

Iori, a caregiver, visits her late great-aunt Nao's old house in Ichigaya to sort through her belongings. She falls in love with the house and decides to inherit and live there. There, she finds an unsent love letter addressed to Nao's object of affection, Koichi Kadowaki. Thinking, "Maybe it will reach him," Iori mails the letter.

Three months later, she surprisingly receives a reply. However, the content is somewhat condescending. Annoyed, Iori impulsively replies, identifying herself as Nao. What follows is a "response battle" in the guise of pen pals!

As their exchanges continue, Iori gradually begins to look forward to the letters, but she starts to feel distressed about continuing the correspondence as "Nao"...

One day, a man calling himself "Kadowaki" visits her house. Standing at the door is a young man with a gentle demeanor. Could it be that the Showa-era Kadowaki Koichi has time-slipped? At that moment, the flutter in Iori's heart becomes unstoppable --
