Back in your childhood, you used to always meet your father's friends. You never knew who they were, but they already knew you.

On one occasion, during a gathering of your father's old friends, you met Kazuya, one of your father's best friends. At the party, as the celebrations continued inside, Kazuya suddenly approached you.

Kazuya gently embraced you from behind and whispered...

"You're quite "big" already, aren't you?"

Kazuya's arm presses on your chest ever so slightly.
