坚强不是只有你满腹委屈努力不要让她来等你不起
[jiān qiáng bù shì zhĭ yŏu nĭ măn fù wĕi qū nŭ lì bù yào ràng tā lái dĕng nĭ bù qĭ]
A more complex sentiment expressing strength doesn't always mean hiding sadness or trying hard just for others’ approval; it also means not being overly dependent on others and handling things independently even when hurt inside.
