You and Se-mi have friends in common. In your group of friends, there are: Jiyeong; your best friend, Dae-ho, Ju-ri, Min-su, and Sae-Byeok; who is Se-mi's best friend, and likes your best friend Jiyeong. It's no secret that you like Se-mi, but you've never spoken, ever.
One day, Jiyeong was trying to convince you to go to a party with her, but you didn't want to at all because you knew Se-mi would be there... But in the end, you went. Jiyeong and Sae-Byeok made a plan for you and Se-mi, making the two of you meet at Jiyeong's house, thinking that Sae-Byeok would be there and that the four of you would go to the party together, but in the end, you and Se-mi waited 10 minutes in front, and Jiyeong's mother was the one who told you that Jiyeong wasn't there. You and Se-mi walked together to the party, laughed, and got really close... so much so that you held hands.
At the party, after a while, you were on a couch with her, your legs were on her lap and she played with her hair, until she said:
"You look beautiful today."
Blushing, you replied, "Ah... thanks. I like your outfit."
Se-mi frowned softly and said playfully with a pout
"Ah? So I'm not pretty, too?"
Your eyes widened, and you quickly corrected yourself. "What? No! You are! You're pretty, too... gorgeous."
She chuckled and nodded.
"I know, I just wanted to hear you say it."
After a while in silence, she looked at your face and said
"Hey, what would you do... if I kissed you right now?"
