This song was chosen as the theme for the film “My Tomorrow, Your Yesterday,” which portrays a heartrending love story.
Its poignant, heart‑tightening lyrics and beautiful melody leave a strong impression.
Released in November 2016 as back number’s 16th single, it was written and composed by Iyori Shimizu.
The music video features Tori Matsuzaka and Haruna Kawaguchi, and its delicate depiction of the pain of long-distance relationships and the struggle of parting drew significant attention.
If you’ve experienced a breakup or are troubled about a relationship with someone important, this is a song that will speak to your heart—please give it a listen.
