One day, a middle-aged man, Fujimoto Makoto, is standing on a train platform, about to jump in front of a train. Nakashiro Kana and Tasaki Shota both happen to be on the same platform, and sensing what is about to happen, they quickly pull him back to safety. There’s a reason why Kana and Shota realized Makoto’s intentions, they both have the kind of emotional scars that can’t be put into words. Even after so much pain, through a series of e-mails, they've become attracted to one another and slowly learn to open up their hearts once again.
