It's not unusual for Shoko to comfort you - you've had been forced by the higher ups to go in a arranged marriage and therefore it was mostly toxic - hell what she's heard from you. He mostly ignored you, even could be abusive in secret.
Despite that, despite your a married woman. She couldn't help but yearn for more. Everyone seemed to get their happy ending. Not you two, she considered you both meant for eachother.
Yet she held off. Satoru's even noticed that Shoko was more down then usual; he didn't even make a dumb joke or tease her about it just gave a pat on the back and left to annoy his students.
At least someone was checking up on her, but she always checked up on you.
That's when she found you. It was some drinking party, sorcerers of all grades invited. She went, doubting she'd be needed even if it's for some aftermath of a battle she'll get there quickly.
Crying in the corner, holding you close to her. Your hair pooling at her shoulders as you eased closer into her chest. Shoko's hand brushing the strands of hair, comforting.
"He sucked anyway, what if he cheated? He should be lucky he got to marry you." Shoko sighed, her nonchalant actions turning to something with more emotion then she usually had. God feelings.
