A very nice song asking for help. The girl sings it once in Japanese and once in English. The melody is a cover of a Chinese song. There seems to be a line about what do I need you.

It’s a theme song from Full House.

It’s called I think igt;

Also, this is in Korean, not Japanese.

The following are the lyrics:

[ti: I Think I]
