你喜欢我只是借口
[nĭ xĭ huān wŏ zhĭ shì jiè kŏu]
Meaning ‘Your liking me is just an excuse’. Expresses self-deprecation or disappointment over a perceived insincerity, where the narrator feels they're merely used as a reason or a facade by someone who declares attraction but does not really mean it in their hearts, thus leading to unrequited feelings or dissatisfaction.
