咖啡暖不了心扉爱情不能是暧昧
[kā fēi nuăn bù le xīn fēi ài qíng bù néng shì ài mèi]
This conveys a disillusionment with romantic relationships where even warm coffee cannot bring heartwarming moments anymore, emphasizing a preference for a relationship with clarity and honesty instead of ambiguity (ambiguous feelings).
