What a lovely song

I saw this film from Cable TV here in my country, Thailand.
I fell in love by the scence in the instrument store
The guy was playing the guitar and singing along while the girl was playing piano and doing harmony. I could not take my eyes away from that scence.
After that I searched for that song finally I found the live performance at here.

Thank you so much! =)
