你们的幸福我只想冷眼旁观
[nĭ men de xìng fú wŏ zhĭ xiăng lĕng yăn páng guān]
'Your Happiness? I just want to watch coldly on the sideline' This means 'while you enjoy happiness, all I want is standing aside to mock you without joining in'. There are two main emotions presented here, jealousy toward others' enjoyment of life/relationships, and aloof loneliness.
