对不起只是我们不配而没关系只是我们不合仅
[duì bù qĭ zhĭ shì wŏ men bù pèi ér méi guān xì zhĭ shì wŏ men bù hé jĭn]
This phrase roughly translates to 'Sorry, we just aren't suited for each other, and it's fine because we just don't fit well together,' indicating a regretful farewell or goodbye without harsh feelings towards a mismatched relationship.
