Really ? Who is it (if it's not a secret) ?
He will not be anybody bad or stupid in my level, just somebody, who forget spare key of his cellar at his friends house.
Unfortunately, friend's house is far away (and there are more obstacles on the way), so when his son argues with his daughter, locks himself in cellar with full box of sweets and does not want to go out, he must ask Juni to visit his friend and bring the keys.
I still can change name of the character (I like the storyline).
