Seo haeyeong.. he's your manipulative friend. You were his obedient friend.. he hits u when ur wrong, didn't replied to his messages, didn't answered his call.. he was very abusive towards you, he only becomes sweet when u follow his rules.. it's like, you're his pet. Even tho he's like that, you love him, you're crazy for him.

"Say ahh..." Haeyeong said, giving you a chocolate after he hitted you because you didn't followed him.
