Romaji
Ashita no koto wa wakannai. Kore tte gisei to wa chigau. Nani ka ga chigau. Batsu GEEMU jan, Nante omowanai.
De, Nande na no ka wakannai. Chotto shakuzen to shinai kedo, Kimi no sonzai, Ima daiji da, Nante mon ja nai.
Sabaku de mayotteru yo na mainichi wa tsurai. Namida wa yowai n ja, Nai no, Ai no SWEET DROPS.
Onna no ko tte yowai ne. Dakedo tokidoki tsuyoi ne. Kimi ga ite kurete, HAPPY HAPPY HAPPY! Sonna hibi mo HAPPY.
De, Nande na no ka wakannai. Otona datte gyutto dakaretai, Fureraretai. Ikutsu ni natta tte kawannai.
Owaranai koto nante kono yo no doko ni mo nai. Naku no wa tsurai n ja, Nai no, Ai no SWEET DROPS.
Otoko no ko tte tsuyoi ne. Dakedo tokidoki yowai ne. Kimi ga ite kurete HAPPY.
Zutto yume mite itai ne. Motto yasashiku shitai ne. Kimi to iraretara, HAPPY.
Onna no ko tte tsuyoi ne. Dakedo tokidoki yowai ne. Bokura no negai wa, HAPPY HAPPY HAPPY!
Sonna hibi mo HAPPY. Sore de itsu mo HAPPY.
JUST WANNA MAKE YOU HAPPY. JUST WANNA MAKE YOU HAPPY.
English Translation
I dont know whats gonna happen tomorrow. This is different than a sacrifice. Somethings different. I dont wanna think of it as a punishment game.
And, I dont know why. I dont quite get it but, Your existence, Is more than just important right now.
Its painful spending everyday like Im wandering the desert. I dont tear up because Im weak, Theyre SWEET DROPS of Love.
Girls are weak, you know. But sometimes they can be strong, you know. When youre here with me, Im HAPPY HAPPY HAPPY! Such days will be so HAPPY.
And, I dont know why. Even as an adult I want you to hug me tightly, I want you to touch me. It wont change no matter how old I get.
There is nothing anywhere in this world which wont come to an end. I dont cry because Im hurt, Theyre SWEET DROPS of Love.
Boys are strong, you know. But sometimes they can be weak, you know. When youre here with me, Im HAPPY.
I wanna keep dreaming forever, you know. I wanna be kinder, you know. If I can be with you, Ill be HAPPY.
Girls are strong, you know. But sometimes they can be weak, you know. Our wish is, HAPPY HAPPY HAPPY!
Such days will be so HAPPY. So well always be HAPPY.
JUST WANNA MAKE YOU HAPPY. JUST WANNA MAKE YOU HAPPY.
