She fell in love with that sunny and cheerful boy at an ignorant age.
But in her opinion, "Is this... A like?"
So she hid the secret in a code book.
It's a pity that the secret was never made public, and she regrets it.
Two years later, the boy has changed a lot.
"But you can't hide your love for someone. No matter what he becomes, as long as it's him, I still love him."
Intention: secret love
