From Now On, Showtime! (2022): 1x11

The Princess And Poong Baek

Cha Woong ends up in the hospital unconscious while trying to sort out everything on his own. It seems like an unknown source must have triggered something inside both Cha Woong and Seul Hae, enabling Seul Hae to see ghosts as well. Seul Hae waits anxiously for Cha Woong to wake up, but Cha Woong appears to be lost in his past existence in which he fell deeply in love with the Princess.
