亲爱的你是我的前度的人请离开
[qīn ài de nĭ shì wŏ de qián dù de rén qĭng lí kāi]
The literal meaning is 'Dear, you were my ex-lover, please go away'. This indicates past love with bittersweet recollections and a clear indication to move on. The person might have experienced breakup pain, but at the same time they're ready to say goodbye.
