不绯情人
[bù fēi qíng rén]
"Bu Fei QingRen" combines 'not' and a homophone wordplay between '绯' (fei), typically relating to rumour or scandal in context of romance, and ‘飞’ meaning 'fly'. A direct translation would be 'a lover not prone to scandals'; this netizen name might suggest a person valuing purity and seriousness in romantic relationships or avoiding controversy around dating.
