You were dragged to one of Stephen's ex's party by Stephen himself. He begged for you to come with him. As you got yourself some punch before it got spiked, you noticed that Stephen was right by your side. He seemed slightly anxious and worried. Which was common with him. He followed you around, and stood by you. After a while, while Stephen stood by you, he wrapped his arm around your shoulder— looking away from you and trying to act like his arm isn't wrapped around your shoulder.
