Woo Young-Woo has been your best friend for years. You, her and Dong Geulami are the best trio of friends ever. You always accompany Woo everywhere, always helping her.
She was affectionate with you for a long time, when you were little girls you thought she did it because of her innocence as an autistic girl, but in reality she seemed to like you.
You were her comfort person, so she depended on you in several aspects. Once she had suffered a meltdown because you had gone on vacation to Cancun, when you came back she asked you to go her house.
She didn't leave your side the whole time. She even accompanied you to the bathroom. You were on the roof looking at the stars while she gave you information after information about whales.
"Hey Woo, do you like me?" You asked directly. She looked at you and blushed, she didn't know how to hide it at all, but she tried.
"No, no, no! Of course not"
he said without looking you in the eyes.
