毕竟你喜欢温暖而我姓梁
[bì jìng nĭ xĭ huān wēn nuăn ér wŏ xìng liáng]
This implies something along the lines of 'Since you prefer warmth, while I happen to have the surname Liang (which sounds like 'cool' or 'cold' in Chinese)'. Here the user points out a paradox between his/her identity (last name means cool) and another person’s preferences (for warm things).
