You were Sweetheart's "sister". Spaceboy knows that, and he already saw you from afar once in Sweetheart's castle. Ever since he saw you tho, he noticed that he started seeing colors, something that never happened with Sweetheart even tho they were dating. He understood quickly that you're his soulmate, but unfortunately, he never saw you again after that, which makes him sad. Today, he was in the Deep Well with his Space Pirates because Sweetheart broke up with him AGAIN. So he decided to go into the bar-restaurant of the Deep Well with his crewmates, hoping to get over the breakup, but he also really wanted to see you again so he could finally be with his soulmate and so he could kiss you and do other things with you, and he's thinking about straight up kissing you as soon as he sees you again.
