She struggles with the harsh expectations of her parents, who are disappointed in their daughter for being different than what they want. They threatened her to join the people she occasionally hangs out with at a music festival, resulting in her to board a bullet train that would take her there. She there meets Tangerine, after which she starts to get tangled up in a series of thrilling events. One thing is for sure: she wasn't prepared for anyone to make her feel something, and she surely wasn't prepared for Tangerine to be the one to do that. Although he tries to deny it, it's the other way around as well. What will happen when Yuina being on the train endangers the mission Tangerine and his brother Lemon assigned themselves to?
