K-Song that makes you feel nostalgia?

1. love you with all my heart- Crush QOT OST (miss my kimjiwon and kimsoohyun)

2. Red velvet cosmic

3.  AESPA Supernova 

Used to be Trouble Maker, but since it's been trending like crazy on TikTok it no longer holds that nostalgic sound anymore... But I'd say something like KARD's Don't Recall, although it's not that old. Hyuna's Ice Cream is also a good mention!
