Who is who's who?

When the happiness went away, stealthily;It was the tears that you could not resist.

When I saw the butterfly flying in the sky;I understood the flower was emarcid when it just blossom.

I would not trust your fictive promise;It was just the cloud that disappears in the sky.

I don’t want to see your alluring eyes;It was just the obvious cheat.

When it appeared again;Should I believe it?Even if, it could capture the happiness in the future;

Could the disappeared heart return?Didn’t cheat me again;Who is who’s who?

Taking your promise, the heart would not be returned.Who is who’s who?I wouldn’t like to be the one whom you want to.
