他不高冷只对我冷
[tā bù gāo lĕng zhĭ duì wŏ lĕng]
A somewhat self-pitying expression indicating someone is not generally 'icy-cold' (aloof/cold-hearted), just specifically cold toward this person. This might express the pain and disappointment felt from someone whom he/she has deep feelings for yet the other person only treats him in a chilly way.
