Seo Soojin would always reject Shuhua's advancements and confessions thinking that she is just another one of her admirers and nothing more, but why does seeing Shuhua with her new found friend Miyeon irritates her so much? "You're jealous"  "So?" "You're not even denying it" Soyeon said with an amused expression on her face. "Shut up"

"Give me 20 days" Shuhua said in serious tone. "What?" Soojin asked confused. "Give me 20 days to prove my love for you. Just 20 days is all I ask and even after that and your feelings for me doesn't change then I'll cancel our engagement, I'll walk away from your life like I never existed in the first place" Shuhua smiled determined to win Soojin's heart.
