Star VS The Forces Of Evil - Chained Heart
His heart was chained down.
Her heart tried to destroy those chains.
Anything she did only made matters worse.
This time, they were at the wrong place at the wrong time.
Marco, horribly injured for possibly the rest of his life, struggles to hide his immense pain from everyone around him. Wrapped in his own chains, Marco tries his hardest to push through.
He must break the chains himself.
But destiny has other plans for him.
"Don't you understand, Marco? You're on completely different sides. You're polar opposites. Natural born enemies. Sun and moon. Mewnian and Monster."
"Because that's all you are. A monster."
