How can a broken me help a broken you...

Before he died, Cup said to the window: "How can a broken me help a broken you..."

My understanding is: when Cup dies, it means that cup is broken. Well. The window was sad, so it was broken.

This is what Brother Erkang said to Ziwei: "How can a broken me help a broken you..."

(Dialogue of Qiong Yao in The Shocking Death)

Also

Ziwei: I know that he loves you so much that it hurts so much, and I also know that you love him so much that it hurts so much...

Erkang: It hurts you, and so does I! It hurts you, and I hurt even more! I'm so heartbroken that I'm about to die!

Ziwei: Erkang...you are too much~~

(...Three...seconds...passed...) Then she said shyly: But I'm fine I like your excess...
