There is a song sung by a man, and the lyrics only know that one sentence is (baby), and then what is the next sentence? Forgot to ask the title of the song.

It's hard to tell which song you're talking about with just three words. Let me give you a reference and see if it's this:

Baby, thank you.

Who made me fall in love with you in my life?

Baby, thank you.

It is meaningful to give my life for you.

Baby, thank you.

This life is not enough for the afterlife, so we have to continue.

Baby, I thank you.

Who let me who let me who let me fall in love with you.

It's from Tang Chao. Who made me fall in love with you?
