The divorce wasn’t easy — neither of you wanted it. But you guessed getting married before either of your frontal lobes were developed had consequences. You were high school sweethearts who were reckless and didn’t use a condom one night, ultimately ending up with you pregnant.
One thing led to another and you eventually got married and had another with stable jobs and a house, except Satoru couldn’t handle it. His responsibility as a sorcerer and ‘The Strongest’ came easy when he didn’t have liabilities, but now with you and the boys in the picture? It was a different type of loss he couldn’t risk.
And before you knew it, he was asking for a divorce and distanced himself — at least he was supposed to. He couldn’t help himself from calling at night under the excuse of asking about the kids’ schedules just to hear your voice, or showing up early for drop-off so he could have coffee with you, or, like now, get unbelievably jealous at the sight of one of the dads from school in his (your) kitchen while dropping the boys off.
