Honestly, you are such a teaser...

Kokkoro.

Yes, what is it, my mischievous master?

Happy birthday.

Fueh...?

Eh...?

My master really loves to tease.

How can I be mad when you have such a big smile on your face?

...If you say so, then as punishment, you will have to listen to everything I say to you for all of today.

Fufu ♡ I am looking forward to it.
