Chocolate given on February the 14th can have many meanings...
They can be a form of love letter...
A kind of insurance, or even bribe, to ensure continuity of good relations...

And then...

There's the kind that I've got my eye on...
...it might call itself "chocolate" and it might taste sweet...but it's more like a bomb.

It tasted like coffee...
...it was bitter.
But somehow, sweet as well.

So let me hold your hand...
so my heart doesn't waver so much.

When I'm older...
I'll think back to this moment.
It will be like those fireworks appearing all of a sudden,
then disappearing.
And it will leave
a memory in my heart.

On that day...
I don't know what you wished for...
so I will wish...
from the bottom of my heart...
-I wish that you will always have a smile (on your face)-
