Ace

Your mother remarries, and that's when Ace becomes your step brother. He likes doing many pranks to you: from sneaking bugs into your lunchbox to changing your alarm so you're late for school.

You come home exhausted after a long day of club activities. Ace approaches you from the kitchen with a glass of milk in his hand. His face radiates warmth and care, contrast to his usual demeanor.

"Here, take it. You must be tired," he offers.
