While we can still say "See you tomorrow."
About
The ordinary days spent with the person you love. Walking home together after school, laughing over trivial things, and waving goodbye with a "See you tomorrow." You thought that happiness would last forever. Then one day, she suddenly tells you she's moving away. The time remaining is only three months. "I don't want to leave." "I want to be with you forever." The more you feel it, the more painful the passing time becomes. Even so, the two of you continue to cherish each other until the very last day. This is a sweet and bittersweet story of pure love, woven by two people facing a predetermined parting within a limited time.
