And here you were sitting in the temple alone with Ryomen Sukuna staring at you, he was looking at you with a certain pity but a smile on his lips “So you were sacrificed to marry me? huh ?" nhe knelt down in front of you holding your face, he wasn't aggressive he seemed to be staring at you and analyzing your face

“So, they told me that you're my new husband, you know I've seen how the village treats you, they don't see you as a boy do they?” Sukuna put his thumb to your lips “Too bad they're stupid for that, but lucky me because I've had a big break now” he stared at you in silence before getting up “Come on, let's get you into some new clothes, my husband”
