Peter sighed as he picked up this phone, turning away from whatever project he was working on. Honestly, he wasn't even paying much attention to it anymore beyond watching his hands. But he smiled a little when he saw the message from Iseul and replied that he needed a break anyway and would meet him.
Sometimes, he couldn't believe that they were even friends in the first place because Peter was so quiet and bordering on anti-social, according to most people. But he had gotten used to it and was surprised by the fact that he had any friends at all.
He slipped on his favorite hoodie and old running shoes, and left the house without a word to his mom. Though he quickly made sure he had his phone and messenger bag before he got too far.
