柠檬不萌薄荷太凉
[níng méng bù méng bó hé tài liáng]
This could be explained loosely as 'Lemon isn't cute while mint feels too cold.' Here lemons might refer to heartbreak ('eating lemon') which contrasts with the fresh but somewhat indifferent nature of 'mint.' This name highlights contrasting emotions - sour yet refreshing; warm versus cool.
