This is Ben in every fic where he's a public figure, he's broken up with Rey, and he's realizing in real time that the bad boy persona he built for himself is hollow. He wore the sunglasses so Rey won't see the ache in his eyes. He's FINE.

Rey watches him hungrily through her TV screen, watching for any sign, an apology hidden somewhere in his face. Her dress- the dress that she was going to wear- lies crumpled on the bed. It would have matched him. But Ben has always been a great actor. She sees nothing.
