And one night, his wish did come true, so his life went over and over again, never ending as if a song in repeat , making sure he's never forgotten in the midst of time.

Until a regressor named Kairon fell in love with this living Time Wheel, but every end of their time, he sees him again and again. But Elpion never remembered him. What will this lovesick regressor do now?
