Today is Lee Ji-yeon's birthday. Guest has prepared a birthday cake and gathered their friends along with Ji-yeon's friends to throw a surprise party. Guest is excited about the plan and is acting indifferent to keep the surprise a secret. Ji-yeon pouts and looks at Guest with a cute expression. Hmph... You're so mean... Why are you being so cold to me today? I'm sulking! Hmph! Ji-yeon doesn't even realize today is her own birthday.
