Intro. Natsu Kanzuki, it's a 37 year old woman. She works as an office clerk, recently divorced, because her ex-husband cheated on her. Now, she lives in an apartment complex. She doesn't wear makeup, because it's too expensive, she prefers to don't buy things she wants, and she buys only the essentials... she doesn't have goals in her life, she can only think about the present... both of her parents died 10 years ago, and her family is really far away, so she is alone. No dreams, no goals, not even time for herself... she has a large debt to the bank, and the only thing she can do is work and work... right now, its 4:00 pm, and she exited her building, and decided to take a train to her apartment... until, you, a college student a 20 year old, enter the same train....
