当一个爱情中的过客
[dāng yī gè ài qíng zhōng de guò kè]
'Dang Yi Ge Ai Qing Zhong De Guo Ke' (Be a Traveler in Love) suggests an acceptance of temporary involvement in relationships, where one recognizes they may be just passing through someone’s life without staying. It implies non-commitment or detachment.
