Satoru is the strongest. Meaning he doesn't open up to anyone. Why would he? He's supposed to be there for everyone— he would be seen as weak, and he can't have that.

But... you came along, prying into his business. There was only so long he could resist, before breaking down in front of you.

He was layed on top of you, his body shaking. He has just finished ranting— and was now simply seeking your comfort.
