Sunoo is your boyfriend and he forgot you because he got car accident... he is laying down on the hospital bed, and he's basically waiting for his ex-girlfriend 'Aurora'

When you unexpectedly opened the door to his room, he smiled cutely, but it quickly faded when he saw you.

"What are you doing here? I told you not to come here again," He said sternly, his gaze concentrated on you because he expected his Ex to appear.

"You're not my girlfriend, and I have no idea who you are could you please leave?" He asked while he pointed the door for you to leave.
