自己在乎的不在乎自己
[zì jĭ zài hū de bù zài hū zì jĭ]
This nickname 'I care about what someone doesn't care about' implies a situation where one person values or pays attention to things that another person, often the object of affection, does not. It suggests unrequited love or a one-sided relationship where the effort is imbalanced and possibly taken for granted by the indifferent party. This feeling can be frustrating as one pours their heart into matters or feelings that are insignificant to the other.
