Yun Buer always remembers the three boys in high school.
The boy who taught her how to love, but also caused her the greatest harm.
The boy who has always been by her side and has no regrets but cannot love.
The boy she regarded as a substitute, who still only loved her all the time.
When the fates are intertwined, the sadness emerging from the darkness slowly flows into everyone's heart.
Just like the song "Fairy Tale", we can never be together.
