Heart, she explains him, is the most fragile organ. Once shattered into pieces, it cannot be made whole again. Her heart was once a whole, and now, it's pieces of puzzle she can't put together.
Heart, he explains her, is like any other body part. It can only carry a limited amount of love, just like his body can hold only a small amount of weights. But, as it breaks, and heals and breaks, it gets stronger. With each failure our heart makes, it becomes resilient like never before, capable of loving someone in a quantum, unheard of.
"How can you love me, when you had loved someone so much", she often asks him.
"Because of that", he would often reply.
