Good night
Walau kemarin kita sedikit bertengkar
Kini tertawa, saling dekap
Ayo kita berjanji (kamu adalah teman baikku)
Walau masalahmu sepele
Jangan kau simpan sendiri
Ceritakanlah, janji sekali lagi
Saat kau tertawa akupun bahagia (sungguh)
Saat kau bersedih kedua matakupun basah
Di dunia ini kamu temanku satu-satunya
Kegembiraan, jiwaku
Akan ku jaga sesuatu yang berharga itu
Selamanya aku bersumpah
Aku mencintaimu teman
Kapanpun aku (di sampingmu)
Memberikan semangat (aku selalu)
Temanmu sepanjang hidup
Jika menemukan film bagus, lagu bagus, cowok baik
Harus beri tahu, kita janji bersama (nononono)
Jangan pelit, saling berbagi makanan
Jari berkait, kita janji (yeah yeah)
Saat kau tak ada

3. Aku sangat kesepian (sungguh)
Saat kau sakit, aku tak bisa tidur karena khawatir
Di dunia ini kamu temanku satu-satunya
Kegembiraanku, jiwaku
Akan kujaga sesuatu yang berharga itu
Selamanya aku bersumpah
Aku mencintaimu, teman
Saat saling bergandeng tangan dan saling percaya
Aku takut pada apapun juga
Walau kata persahabatan terdengar canggung
Sepertinya diciptakan untuk kita
Temanku….
Di dunia ini kamu temanku satu-satunya
Kegembiraanku, jiwaku
Akan kujaga sesuatu yang berharga itu
Selamanya aku bersumpah
Aku mencintaimu, teman
Kau adalah hadiah hidupku, temanku
Permataku, keajaiban bagiku
Aku terus menjaganya
Aku bersumpah sekali lagi
Aku mencintaimu, teman
Membuat julukan dan bercanda
Terkadang bertukar pakaian bagus
Nomor teleponku di tombol cepat mu
Dan juga jadi teman sepanjang hidup
Selamanya kau temanku
Satu-satunya temanku (yeah)
Satu-satunya temanku
