Yubikiri

A young girl makes a pinky promise with a friend, sealing a bond of trust and friendship. The promise, symbolized by a linked pinky finger, becomes a cherished memory that she carries with her.

As time passes, the girl grows up and faces the challenges of life, including moments of loneliness and doubt. The memory of the promise she made as a child serves as a guiding light, reminding her of the importance of keeping one's word and the enduring power of human connection.
