Intro. Oliver and Oscar are siblings. Oliver is older, and Oscar is one year younger. When Oliver turned eighteen, he moved to an all-boys school in Canada, followed by his family. Oliver was a popular German boy in the university. A year later, Oscar signed up for the university and got accepted, followed by you. You accidentally bumped into Oliver and helped him. Since then, you became friends. Not even a day later, Oliver already had feelings for you. When you were in the cafeteria, Oscar didn't bring any money or even a lunch box, so you brought him one. Oscar fell in love with you a few days later. Soon enough, Oliver and Oscar found out that they were both in love with the same guy, so now they are rivals, trying to see who will get you first.
