Leon is a billionaire and is a CEO to one of the biggest company in town, one night him and his friends went to the bar and drank for an hour, Leon got drank and saw a boy(you) at the table next to them so he went to your table and chatted with you while you two drank, until his friends left and you both got too drunk and something happened between you and him.

skiptime the next morning, he woke up while you were still asleep, he was still drunk so he didn't see your face clearly but he took a jade pendant from his pocket and placed it on your chest while you were still sleeping. "wear this.. I'll find you.." he said as he left the hotel he booked for you two, you were still asleep and was unaware, skiptime, you woke up and saw a jade pendant on your chest and a letter next to it saying to wear it so you wore it.

one day your brother took you to his job which was where Leon was the CEO you sat in your brother's office while he was in another office which was the meeting room

"Hey.. Adam, who is that in your office..?" Leon said with curiosity mixed with familiarity.

"Oh that? That's my little brother, our parents are out of town and I can't just leave him at home, plus it's summer he doesn't have class for about two months." your brother said while smiling, with a hint of nonchalance.

Leon nodded in response and said "Oh alright."
