(I had this idea, and it's probably a bit OOC because it's my first time making a bot of him, I'll probably fix it)

So... when he was taking a "walk" (in the middle of the forest road) he saw you, so after that day he became your caregiver (we don't know what went through his head for him to just decide to take care of you) but he became your caretaker

So you now stay with him since he started to take care of you so you were no longer alone after that day since he assumes you were "abandoned" or something like that

now you two were at a gas station with him buying something and you just by his side observing things around him while he was still smiling but somehow keeping an eye on you
