Winter diary
Silent night, holy night
All is calm, all is bright
We can feel the love tonight
I haven't stopped, I'm still constantly writing
in my heart's diary
As the nights we can't spend together increase,
the more precious the way you smiled too close to me becomes
Maybe I'll cast a spell on the pure white snow
and go to you to tell you now
the words I couldn't say before
Blaming it on this white season,
I'll say "Let me stay by your side"
like that summer back then
