深巷的少男我爱你旧街的少女我想你
[shēn xiàng de shăo nán wŏ ài nĭ jiù jiē de shăo nǚ wŏ xiăng nĭ]
This is romantic and nostalgic. 'A Boy from a Deep Alley I Love, a Girl from an Old Street I Miss' expresses affection towards young love and longing for something lost, possibly indicating that first love can't return but has been engraved in memory.
