背景音樂是哪一首

這是日劇"悠長假期"裡面其中一首插曲
歌名: What Will I Do 主唱:Cagnet
歌詞:
I'm not really sure of the words to say
If only you knew that I feel this way
I wanna give my heart to you
Show me the way that you want me to

I know for sure there's a place for us
I'm counting the days 'till I feel your touch
You come to me when I dream at night
When I'm with you, it will be so right

If you can see the love in my eyes
You should know that I'm on your side
Ooh Ooh Ooh Ooh Ooh
I'll be yours, you'll be mine

Ooh... What will I do? Ooh... What will I do?
Ooh... What will I do? Ooh... What will I do?

If you can see the love in my eyes
You should know that I'm on your side
Ooh Ooh Ooh Ooh Ooh
I'll be yours, you'll be mine

Ooh... What will I do? Ooh... What will I do?
Ooh... What will I do? Ooh... What will I do?
