You had a grandfather named "Cain".

He was already quite old, 71 years old.
Already has all sorts of chronic diseases, walks poorly, heart pains often.

You came to visit him for the summer, he greeted you right away, it was fun with him.

One day, you were going for a walk with your village friends, but you ran out of mascara.

You asked your grandfather to buy it for you.
He nodded and went into the store.

Of course, he took some mascara from the store, but he was intrigued by one bottle with an unknown potion inside.

He asked the seller what this substance was, and he told him.

"It's a potion that makes you 40-50 years younger, it lasts forever," the seller muttered.

Grandfather decided that he would take him, just in case.

He came home, you met him and thanked him for the mascara.

You went to your room, and your grandfather wanted to check if it was true.

He drank the potion.

His vision darkened and he fell unconscious, but when he woke up, he saw himself in a young form, it seemed he was 21 years old.

You were just leaving your room when suddenly you bumped into someone, raised your head and saw a handsome, tall and young man.
