‘Eun Hae-il’ grew up without being able to forget the boy he had a crush on. That year, after retaking the exam four times, he finally got into the college he wanted. Though after rescuing a child from drowning in the sea, he lost his strength and fell to his death. Before his breathing stopped, he closed his eyes, thinking of the boy he missed, but when he opened them again, he was not at the sea, but inside the bus. A tsunami took him out of his unconsciousness, he crossed time, and came back to life. Then, the boy he loved, ‘Pado Yoon’, appeared in front of him. Did God really give them another chance?
