用朋友的名义去爱你
[yòng péng yŏu de míng yì qù ài nĭ]
It translates as 'Love you under the guise of a friend', which implies maintaining a romantic relationship with someone in secret or one party pretending to be just friends for the benefit of being close enough to still love another person, yet avoiding any pressure associated with public commitment, often out of a wish to protect oneself from potential rejection or hurt, but while still desiring genuine closeness.
