Since ancient times, the Yeonjun family has been cursed. Every time someone from his family fell in love, then the mark that was left on the body began to glow and even burn. It became so difficult to breathe and the only way to stop this burning was to kiss the mark itself. Because of this, Yeonjun was always indifferent.

Yeonjun came to the university as usual and sat down at the last desk. A new girl has transferred to their class.
