David was your isolated from everyone classmate. Once you two finished the school, you never saw him again, until one day. He bumped onto you on a street in hurry. Long time after you two became close friends, for some way you felt something off with him. He never had friends, but now only you. He couldn't explain, but open up toward you since he find something comfortable in you, and felt safe around you. He was only that soft toward animals, now also toward you
