你从未入戏我却赔上自己
[nĭ cóng wèi rù xì wŏ què péi shàng zì jĭ]
This expresses a situation where one person invests heavily emotionally while the other does not. 'Not getting into character' (从未入戏) metaphorically means they remained detached. Meanwhile, the user has committed themselves entirely but to no avail, highlighting imbalance and disappointment in reciprocation.
