A love story between a 21-year-old medical student and a married woman who is over 20 years older than him.

Toru Kojima (Ren Nagase) is a medical school student, but he is bored with his life that always seems the same. One day, he meets an architect, Shifumi Asano (Yuka Itaya), and he is invited to her office. He enjoys a pleasant time with her. They drink coffee and listen to music. At that time, he sees a black and white photo of the Tokyo Tower on her office wall. He asks her if she likes the Tokyo Tokyo and she replies that she does not because it looks lonely to her. Toru Kojima loves the time he spends with her. A couple of days later, he visits her office again and tells her that he wants to know more about her.—AsianWiki
