Totsuzen arawarete ore o kaeru nante 
 Arienai koto dayona dakedo okottanda 
    Konjiki no taiyô mado kara yettekita 
 Muriyari kojiaketa ore no mune no tobira   
 Hamaranai pazuru niwa ibasho ga kieta sekai 
 Se o mukete suwatteita kono heya wa marude sheruta   
 Kanashimi no tame ja nai kizukasete kureta 
 Shinjite kureru no nara ore mo kotaeyô 
 Yomenai kotoba ga aru kono hon wa kitto 
 Kokoro no chikara dake ga kotae nandarô   
 Kanashikatta koto ni kizukasareru nante 
 Kuyashii kuyashikute totemo ureshikatta   
 Tsuyogari no sono senaka hiza yori mo hikui noni 
 Ore no koto mamoru nante mô nidoto iwasenai ze   
 Kanashimi no tame ja nai hokori ni omou yo 
 Boroboro no fuku de sae nazeka itoshii 
 Kedakai kizuna o ima musubi hajimeteru 
 Kokoro no chikara dake o kate ni shinagara   
 Kanashimi no tame ja nai kizukasete kureta 
 Shinjite kureru no nara ore mo kotaeyô 
 Yomenai kotoba ga aru kono hon wa kitto 
 Kokoro no chikara dake ga kotae nandarô     
 Translation   
 He appeared suddenly and said he'd change me 
 It seemed impossible, right? But it happened   
 The golden sun came in from the window 
 And forced open the door of my heart   
 In the puzzle that won't fit is the world where my place has disappeared 
 This room I sat in with my back turned was like a shelter   
 It's not because of my sadness, you made me realize 
 If you will believe in me I will answer that 
 The power of the heart is probably the only answer 
 To this book with words I can't read   
 I was forced to realize that I had been sad 
 Vexing, I was so vexed -- and very happy   
 Your back, showing courage, though you don't even reach my knee 
 I will never again let you say that you will protect me   
 It's not because of my sadness, I take pride in this 
 I somehow feel love for even your ragged clothes 
 We have begun to form a noble bond now 
 Feeding only on the strength of the heart   
 It's not because of my sadness, you made me realize 
 If you will believe in me I will answer that 
 The power of the heart is probably the only answer 
 To this book with words I can't read
