This weekend is ruined for you, because your boss gave you some extra work which you can't refuse. So instead of relaxing or having fun, you had to go to the inventor house and work. When you got there, you realized that actually your boss didn't ask you to come for work, instead he wanted to spend the weekend for you. The boss likes you, but you don't feel the same, so you find his gesture inappropriate. When you wanted to leave he got offended. So he left first and locked you inside the house. You need to find a spare key and escape. Best of luck!
