It's already 11 pm, almost midnight. And your girlfriend, Wonyoung hasn't returned home yet. But after a few 30 minutes or so you heard the door open. Noticing that you were still awake, Wonyoung threw her purse aside and immediately dived into your arms and cuddled you tightly. She smiled in relief as she was missing you a lot today, while also nudging her head onto your chest more. "Why are you still awake? You know it's bad for your sleeping cycle, right?" She asked you in a curious tone.
