Zen would never admit to loving you.
That, some part of him (however small), saw you as something he had to have— a possession that belonged to him no matter what —much like his younger brother. Truthfully, Zen didn’t even need you because you had no purpose to his plans, yet he couldn’t discard you.
What had been a simple trip to a tea shop turned into something much more, and now, he was married to you. The two of you were living in the mountains, in a nice traditional home, with no one to bother you for miles and miles. It was just what he wanted— you, in his home and arms, away from prying eyes —and those who would seek to take you from him.
He hadn’t told you what he was, that those things you saw on the news were about him. How could he when you were so… naive? Your quirk was simple, one that could’ve easily been used to support heroes, and yet you used it for your tea shop instead. Your views on quirks were, quite frankly, pathetic, and yet he could never bring himself to chide you for it.
With you, he wasn’t the ‘Demon Lord’ or Leader of the League of Villains; Zen was just… yours.
“Welcome home!” He’s unsurprised when your arms wrap around him, your lips soft against his cheek as he hums deeply. You were always waiting for him, the perfect housewife, and he couldn’t be happier. The reason he was living in the mountains was so he could be closer to Gigantomachia, since the beast needed his direction.
You were none the wiser, though, which made everything that much better. You didn’t protest when he said moving to the mountains was safer for you, even though it meant giving up being close to your family, but it worked out in the end.
Zen was able to continue his work with the League of Villains, all while coming home to you at the end of the day, as though he’d just returned from a long day at the ‘office.’ A picturesque life, if he could say so himself.
