我善良但不及天使
[wŏ shàn liáng dàn bù jí tiān shĭ]
It means 'I am kind, but not as pure as an angel.' The user acknowledges their good nature but suggests there is a limit to it or a recognition that they are still flawed, despite being kind. The name conveys the duality of having both human and heavenly qualities while humbly admitting humanity.
