Rei didn't want to marry Enji. It wasn't a choice she had. It was arranged by their parents because Rei's ice and Enji's fire are so, so strong.

(She thinks she would have preferred Kushina, with her loud nature and boisterousness and stubbornness to do what she believes is right but two women can't have a child and Rei's been promised to Enji and Kushina's been promised to some other guy.)

Rei marries Enji anyway, because her parents want her to and she wants to make her parents happy even if that means marrying a man she doesn't love. So in the end, she has no choice in her marriage.

(Except she does- Kushina took her arranged marriage by the horns and defeated it and Rei's just too scarediwanttomakemomanddadproudIdontwantthis to fight)

They don't learn to love each other but they learn to care for each other. They learn each other's sense of humor and favorite foods, they have dinner with each other's family. They have a son, and through the thick fear in her chest she names him Touya.

Nothing changes and life goes on. They take care of Touya, who gets sick too easily. They have fun. They don't-quite-love each other (but it's so, so close).

And they have a daughter, only a year later. The fear is there, again, but it's not as strong. She names the baby girl Fuyumi, after Rei's grandmother, who the girl looks just like even at this age.

They're happy. They're happy and then they're worried because Touya's quirk burns him and they don't know what to do. Enji pulls away in his desperate search for a cure. Rei watches as he yells into a phone, angry and sad and worried and scared all at once. She looks at Fuyumi, who's sweet snow quirk was overlooked in the chaos, at Natsuo who's so, so young but who is still so affected.

She calls Kushina.

The woman arrives in the whirlwind of energy she's always been, with news of a husband and with soothing words that pull Enji back to them.

(Rei ignores the burn of jealousy at Kushina's husband. She -loves- likes Enji well enough and that's all she could have asked for, in this situation)

They're happy again. Nothing's changed (everything's changed).

(Abuse starts when Natsuo shoves off his weak ice quirk and his sensitivity to the heat and chill. It continues until Touya -dies- joins Kushina's family. It continues until Rei can't bare to love Enji anymore. It continues until Rei sees blue and red and thinks Enji when it's only Shouto. It continues after Rei is in a mental institute, crying over her mistakes and wishing so, so much that she had fought back against her parents all those years ago.)

(Except she had loved Enji and she loves her children and all she really regrets is how being famous changed her husband into someone unrecognizable.)
