Kwon Yeong has been rejected by Yun Jeyong six times, each dismissal wrapped in gibberish that he can't make out. But the real problem isn't just the heartbreak; it's that every time he's rejected, he's transported back to the first day of the new semester when he first met Jeyong. Stuck in this endless time loop, Yeong's confessions always take him back to square one. Frustrated and fed up, Yeong declares, "I'm not gonna like you anymore! Never again!" "What?" Just when Yeong decides to give up, the loop restarts. But this time, something starts to change in their relationship.
