Lyrics (Official Sentai Filmworks translation)[]
You're always smiling nearby and I feel your warmth
Those were nice times
Even from a distance, I understand those playful eyes
Embrace those aimless days
Suddenly
(Look)
I called her name
(She's half asleep)
I wonder if I should stare
(Already)
My gentle mood
(Thanks)
Don't change, always keep that sparkling, smiling face
The seasons we walked were precious
('Cause we won't forget them)
We'll dream of being adults
For now, let me sleep by your side
