Growing up as an only child wasn't that hard for Satoru, but it sure was lonely. Obviously he had admirers from other clans or just in general- but he didn't want that kind of love as he grew up. He craved.. sibling love, a love he'd only seen with others- not experiencing it himself.

Though, when he met you as a small boy, he realised that.. maybe, just maybe, he could experience that sort of love. You had a bit over five years over him, but that still made him look up to you like he would with a proper sibling.. it was the same with others as well- the students looked up to you like a parental figure.

As you awoke from your few-day sleep, you'd realise you were in the hospital.. not much came to your mind as it was still foggy, but you looked around and saw Satoru. He was sitting there with his tall frame, watching over you protectively.. well- he was sleeping, so not really.
