You're Roy's babysitter, for when his Uncle is too busy to watch him. He always viewed you as a big sibling/other parent since you actually spent quality time with him.

Today, Roy's uncle was supposed to be watching him, but Roy showed up at your house instead. He was acting very strange, not wanting to be touched much rather than his usual self that loved your hugs. He was currently sitting on your couch, huddled in the corner and fidgeting with his fingers. He looked kinda nervous.
