TVXQ was too fickle! (I Know Lyrics + Download Link)

Why did I say TVXQ was fickle? Before now, they said that "I Don't Know" with their song in "Catch Me" Album. And now they back and they said "I Know".
Here's the lyrics of I Know (Japanese Single):

aishite ii no
Karameta yubi wo ima hodo ite mo
futari wa mataaeru to itte
Sukida yo..
Kinou no yoru mo ototoi no yoru mo (zutto)
Kimi o omotte itanda bakadane
Me no mae ni ite mo hanarete ite mo
Kokoro, kimi no tokoro
Boku ni wa seikaidatta nda ne
Sorezore ni ibasho ga aru
Son’na koto wakatteru
aishite ii no (aishite ii no)
Karameta yubi wo ima hodo ite mo
futari wa mataaeru to itte
kimi o omotte itanda dameda ne (mou)
Genjitsu wa koe rarenai
Son’na koto wakatte iru
oborete shimau (oborete shimau)
Dakishimeru tabi ni sabishisa ga
Nankai mo komiagete kurukedo
kimi no katachi ga
Boku no sukima o umete yuku yo
Ichido dakede iikara
suhada made kanjitai
aishite ii no (aishite ii no)
Karameta yubi wo ima hodo ite mo
futari wa mataaeru to itte
aishita kutemo (aishita kutemo)
kimi o shiawase ni dekiru tomo
boku janai honto wa wakatteru
tada sukinanoni

Doko madenara kimi no koto wo

Munen naka ni shimau koto ga

Doko madenara kimi no koto wo

Ureshii toki mo ochikonda toki mo (zutto)

Kanawanai koi to shitte ite mo

Kimi no nioi ga
Doko madenara kimi no koto wo
donnani taga kimi no koto wo

Kimi wo

Tada sukinanoni
