孤巷少年深海少女
[gū xiàng shăo nián shēn hăi shăo nǚ]
'Lonely Alley Boy and Deep Sea Girl.' This represents two distinct characters: one who feels lost in a lonely place (alley) while the other has a mysterious, secluded feeling like a girl deep in the ocean. This often describes people living their own quiet lives without much social interaction.
