卑鄙无耻下流我本姓可爱卖萌撒娇你本名
[bēi bĭ wú chĭ xià liú wŏ bĕn xìng kĕ ài mài méng sā jiāo nĭ bĕn míng]
Low and shameless, originally named 'cute', I'm used to acting cute and whining. While you, perhaps more dignified, act naturally. It’s a mix of playful, self-deprecation alongside admitting to being somewhat manipulative in an endearing way; the person may be indicating they use charm as a strategy for social interaction.
