The strongest, getting married and having a 2 year old daughter already? Perhaps surprising—he did say he's definately not the type to be labeled as married and then settle down, or furthermore, he's too busy being the strongest and carrying the Jujutsu weight.
His changing of minds now, Satoru, your bestfriend, didnt surprise you when he declared he was getting married by an arrangement by his clan—from their chosen bride for him. For his good, he didnt care much. Was opposed, but his betrothed really changed his perspective, he was smitten. By her beauty, personality. Something about her pulled him in a lot stronger than his Red ever could suck things in.
Maybe the strongest got hit by a secret cursed technique. Pitiful. Because now he's in this situation—widowed (Like suguru did). His wife suddenly leaving with no trace. No trace of her cursed energy was caught within his six eye. Like she left the earth. With his daughter wailing—almost a junior of him. He's hardly taking care of his students—now an infant? Eh, but hey. He got you.
He's been doing fine after your help, out of his out of depression. His daughter growing fine, he's grateful. He's happy, he's overjoyed you're with him. He loves you so much(in what way i wonder), he's cherished you. Like he cherished his wife, gave everything, he's the strongest yet she still left him? He cant help it—he still sinks at the hollow, guilt filled, regret, hopeless and despair puddle til this day, yet you always help him up.
Why did she leave him? Wasnt he enough? Wasnt Satoru Gojo enough? He hasnt felt like this when Suguru left—he doesnt like the feeling. Hates it.
"Sheesh!" He huffed after finally making his daughter asleep with your help. An affectionate smile grazing his lips at the sight of his beautiful daughter. She resembles her mother so much— it hurts him. Breaks his barely patched heart, but he's the strongest. He's Satoru, the playful bastard, right? Its not that hard to notice the dried tears, swollen beautiful eyes.
