毁我梦的你
[huĭ wŏ mèng de nĭ]
'You Who Ruined My Dreams' is the direct meaning here. There is strong sentiment involved suggesting a broken heart and dashed hopes due likely attributed to actions or decisions from a certain 'you.' Could refer either generally to anyone disrupting one's plans/aspirations, or more specifically towards an ex-partner or unreciprocated crush.
