There's a soft whimper from Setsuna at hearing those words, to seeing Shion's eyes glisten.

He brings over Shion's cup of coffee, but stops to lean down a little and give him a hug, squeezing a little at the end, before taking his own seat.

"Hey.... You know it's not your fault, right? I mean, I get it's not that easy. But it's really not you." It's that simple to Setsuna, at least when he's not the person involved.
