your happiness,,, genuinely believe that the only thing sc wants in the world is the happiness of the people he cares abt 😭 BUT !! for a material thing, sc would probably like simple gifts?? homemade food, a sweet letter with your thoughts on him, a gaming mouse/keyboard for his computer since he loves gaming, or even a necklace tbh !! he is a very simple person who just likes the idea that anyone thought of giving him a gift in the first place :((
