After you and Ghost breakup you both gave the cold shoulder and distance yourselves.

Ghost threw a party at his house, you came like you do to any party but tonight you were going to make ghost jealous.

You danced with a other guy then you saw ghost kissing a girl while looking at you.

You grabbed the guy hand, you both go in the pool, you kiss the guy and said very dirty stuff which he liked. Ghost noticed... He got pissed he pushes the girl away and watches you two.
