多情人被癡情殤
[duō qíng rén bèi chī qíng shāng]
"Duo Qing Ren Bei Chi Qing Shang" translates as ‘The person full of feelings is injured by the blind/loyal affection'. Here, 多情人 stands for those who fall in love easily, while 癡情人 refers to one's loyalty or obsession towards someone in love. So this username implies the user suffered emotional damage from a loyal/obscured relationship.
