听说小三喜欢小四
[tīng shuō xiăo sān xĭ huān xiăo sì]
Roughly meaning 'rumor says that the mistress likes her friend,' this name reflects a gossipy situation where affairs of relationships (often involving infidelity) between people are discussed. It refers to the third party involved in the love life ('mistress' in English often conveys this role).
