Doushite kimi wo suki ni natte shimattan darou?
the last verse especially is so sad ;
Sore demo kimi ga boku no soba nara to itte mo
Eien ni kimi ga shiawase de iru koto
Tatoe sore ga donna ni sabishikutemo
But, even though I say that I need you close to me
I just pray that you will be happy forever
No matter how lonely that makes me (or how sad)
