Chichin Pui!

Ren has long had feelings for her childhood friend Chikara, who is fascinated by the supernatural. While walking home, she assists an elderly man who collapses in the street. As a token of gratitude, he gives her a small doll made from wool string, claiming it can help with matters of the heart. Confused about how such an object might work, she is left wondering if it could have any real effect on her situation.
