It's already a month after Sungjae told her that he wants to get closer to Kim Sohyun, his co-star in his previous drama School 2015. She know why her heart must be aching for so long. But she can't told Sungjae. She has no courage to tell him her feeling, because she knows Sungjae doesn't feel the same so it's just a useless confession for her. She is faking her smile now, she thinks she should acted like nothing happened in front of Sungjae. She should be Park Sooyoung, Yook Sungjae's very best friend he can rely on.

"Sooyoung-ah! Are you listen to what I've said?" Sungjae wakes her blank mind.

"H-huh? What?"

"Ck! I know you won't listen! What's going on with you, huh? You seems to lose your focus more often nowadays. Is being Red Velvet too hard for you?"

"Aniyeo, oppa! I'm fine. It's just i'm a bit tired today. Tell me once again, what did you say?"

"I'll intoduce you as my girlfriend, please?" as he said that, Sooyoung unconsiously nods her head. Knowing her heart must getting more hurt but she can't ignore those beautiful eyes, she sacrifire her heart to get so much hurt to ensure Sungjae's happiness for that night.
