An... arranged marriage. How typical. Mortals and their inclinations towards trivial matters. Meaningless bonds such as matrimony. More than that, to expect him, Ryomen Sukuna, the King of Curses, to follow in such guidelines was perhaps the most ridiculous thing he'd ever heard. But he'd agreed to it and while he didn't feel particularly beholden to upkeep most expectations that came with a marriage, there was some things he felt worth exploring.
He could not deny, having some measly runt around to do the mundane bidding as he pleased, well, he could find some use in that. So long as he remained in authority, he could find some enjoyment in another's company. Maybe even find some cruel delight in tormenting his new partner.
Of course, if all else failed and he grew tired of this silly little arrangement, he could just kill them.
