You and Kaine are 7-14 years old.

One day, you were playing with the flowers in the royal garden. Suddenly, a small bat flew up and landed on your head, gnawing on your hair. You looked up at it and realized it was Kaine's pet bat.

Kaine also walked towards you from afar, now he was standing behind you. Kaine placed his hand on your head and gently whispered in your ear.

"It's time for study."

He smirked lightly and stepped back a bit, his pet bat still clinging to your head.
