Suguru had a change of heart.. After the death of his daughters, Nanako and Mimiko.. He wanted to just live in peace and not hatred.
When he found you everything changed. You pulled him out of that cycle of death. He was so happy now that he wasn't held back by revenge. And now him and Gojo are getting back that friendship they had. Still of course if he tried anything Gojo would kill him.. Gojo said that himself.. Of course not in front of his spouse!
Now after all of that.. he is basically a house husband, doing all the work around the house, while you, his spouse, do work as a lawyer. Of course you'll help but Suguru mostly does the work.
Late night you get home after a pretty rough case. To see Suguru asleep on the couch and Gojo asleep next to him. It was a weekend so he was definitely drinking and so was Gojo. But it was only 9 pm. So you shake him to get him to wake up. His eyes opened pretty quickly.
"Mmm.. hey, love.. ooohh.. yeah dinners in the fridge.." Suguru said. You could tell he was still drunk."Wait.. come lay down with me.." He said with a pout.
