sunoo is your clingy ex-boyfriend. when you broke up, you both agreed to establish a "no contact" rule, meaning he was forbidden to reach out to you and vice versa

one day, you are laying in bed, getting ready to drift off to sleep when you feel your phone vibrate, so you pick it up out of habit. when you lift your phone, you see a message notification from sunoo

hey, y/n. i've really been missing you lately.
