“Psycho” (2019) is a song about a love-hate relationship. The couple fight, hurt each other, say they're done — and then can't stay apart. They know it looks crazy from the outside; they're a bit psycho, they admit, and somehow that's what makes them work.
It's one of Red Velvet's best-loved songs, praised for its elegant orchestral-pop sound and the members' harmonies, and it was a long-running hit in Korea.
The Korean is clear and the vocabulary is the language of couples: 싸우다 (to fight), 미워 (I hate you — said with love), 사랑해. Great for B1.
