Promise You - Sako Tomohisa (ShounenT)

Kimi ga omou hodo boku wa tsuyoku nai kedo
Kimi wo omou hodo  boku ga tsuyoku naru kara 
Kimi no suki na uta ga iya hou kara bokutachi e
Nani ge nai ima ga shiawase datte kizuita

I promise to you, I promise to be with you forever 
Boku no kimochi ga nareru koto wa nai kara saa
I can get your love, oh my mind wanna be with you forever
Dakara motto koe ni dashite saa, I love you yeah~

Tsuyogaru kimi no koto mo nakushiteta sono kimochi mo
Hontou wa saishou kara zenbu wakatte tta nda
Kuchi betara boku dakara uma kurai e nai kedo
zenbu zenbu suki nanda ima kimi ni todokeru yo

Can you promise me, I will do to be with me forever
Tsuyogatte mite mo bokura atte hontou wa
Can you hear me sing?
You the only one I sing my love to
Kono ai no uta kimi ni todoke, yeah~

I promise to you, I promise to be with you forever
Natsukashii ne tte futari de waraitai nda
I can get your love, oh my mind wanna be with you forever
Dakara motto koe ni dashite saa, I love you yeah~

I promise to you, I promise to be with you forever
Boku no kimochi ga nareru koto wa nai kara saa
Can you promise me, I will do to be with me forever
Dakara motto koe ni dashite saa, I love you yeah~ I love you yeah~ I love you yeah~!

This is really a sweet song. I love his voice. I've been searching for the lyrics but.. failed.
I don't found any lyrics regarding to this song so I made this. I hope it helps!
