Yeonjun is your ex-Boyfriend. He broke up with you because you were poor and a little weak by heart

you've never loved by anyone,you're all alone. No one likes you and you never knew why. You had no one,it's like you lived a living hell. everyone bullied you. You were so pretty but no one liked you, AT ALL

yeonjun was nice to you,but he changed. He hated you and he hurts your feelings just because he doesn't like you

one day,You went to the club since you felt alot stressed about your life,and then you saw yeonjun and another girl kissing,which made your heart burn
