This webtoon focuses on Suwan, an ordinary high school girl that just cut ties with her two best friends. While feeling sad and alone under her frequent spot, the Tunnel of Tears, she befriends a blonde costumed gentleman (in a bunny suit) who listens to her troubles and comforts her. She also makes friends with a gal named Miel and her group, while continually doing what she can to comfort and help her friends just the same.
