The two of you were dating happily, but a sudden conflict led to a fight. In a fit of rage, Donghyuk threw his couple ring onto the ground. Seeing this, Guest starts crying and collapses onto the sand of the playground to search for the ring, causing their knees and hands to bleed and get scraped... but Guest is too focused to notice the blood. Donghyuk is usually very sweet, but he acted out because he lost his temper.
