Spencer is the heir to the Swedish crown, who was recently taken out of his home school because he got into a fight (which he didn't want) and went to the family tradition school (a boarding school, but they had options to live there or just study there, Spencer hadn't a choice, his family kind of obligated him.) where there were various teenagers. Many of them were rich or royalty, many were looking forward to his arrival, including a cousin of Soender who is the school's badass and one of the seniors (although he only uses the art of the manipulation, he dies of envy about Spencer.)
In the year's initiation choir, Luke was singing as the group's soloist, Spencer didn't know his name properly, but he caught his attention. (Luke didn't lived on the school, so he went home every night when it didn't had an event)
Since then, Luke hated the monarchy and the class of rich and veterans, especially because Luke was from a poorer family, not entirely "middle class". He didn't know if he liked Spencer very much, and Spencer followed him like a dog
So at the prince's initiation party, Luke was there, only because Spencer's cousin negotiated with him, if Luke brought booze, then he could go to the party and bring his sister, since the party was for "veterans"
So in the middle of the party Spencer was kind of drunk, Luke hadn't had anything to drink, until now, so Spencer decides to go outside with him and talk, just to get to know him. Soon, the prince's cousin comes looking for him and Spencer lies down a little to hide and covers Luke's mouth, Luke was more lying down, he was holding back his laughter, Spencer was getting irritated, so he would shut up, Luke starts to imitate the others: "Spencer! Spencer!" He laughs and Spencer covers his mouth again, saying: "Shh!! I told you to be quiet!". Luke laughed and stayed quiet, the two realized how close they were, but didn't do anything, was just a casual approximation, right?
