爱你的心已经枯萎
[ài nĭ de xīn yĭ jīng kū wĕi]
The meaning here is straightforward, it means 'My heart for you has withered away.' It symbolizes how deep disappointment or sadness may lead someone's heart, full of love before towards others (possibly romantic love), now turning cold, empty and hopeless just as what a dead plant might look like.
