[1] Every morning, Sun-woo receives a calla lily with a musical note attached to it, and he wants to find out who his secret admirer is.

Wanting to confess his feelings for her, he asks her out on a date at a local hotel, and she agrees.

At the hotel, though, he arrives to find Ji-hee taken hostage, and, to his horror, tragically murdered before his eyes.

His desperate wish to revive her magically comes true whereby time is turned back to the day of the fateful date at the hotel.

With this, he is transported back to the present, to begin the quest for his true love, Soo-jin.
