What songs' MVs make you unforgettable for a long time?

JJ Lin's "It's a pity that there is no if" was the first MV I watched.

This movie, starring Angelababy and JJ Lin, tells a regrettable story. As the lyrics say, "It's all my fault. You shouldn't be silent when you are silent, but you should be cowardly when you are brave. If it weren't for me, I would misunderstand myself, be free and easy, and make us sad. " In my feelings, it's a pity that I missed it, leaving only the result, but unfortunately there is no if.

I feel that this MV is particularly nice, especially the songs, which used to be a single cycle.
