咱在霸道也只是对你一个
[zán zài bà dào yĕ zhĭ shì duì nĭ yī gè]
'When I am arrogant, it's just for you.' This kind of username expresses the exclusiveness and specialness of one's feelings or attitude towards a particular person, implying that although one may seem arrogant in general, this behavior is only exhibited towards the specified person.
