AU where Sukuna was still in blob form when Yuuji first encountered him, so Yuuji (who knows nothing of Sukuna’s past or reputation) felt bad for him and took him in to take care of him (yes, the blob says evil things, but he obviously can’t do any of them, and he’s SO CUTE)

Despite all his “love is worthless” spiel, Sukuna ends up falling in love with Yuuji, and who can blame him, when Yuuji oh-so diligently feeds him good food and keeps him nice and warm all the time?? But he also gets super frustrated because, since Yuuji doesn’t view Sukuna as a threat or take him seriously in that way, Yuuji unintentionally taunts him all the time by doing things like undressing in front of him, showering in front of him, and just being a huge tease in general, and Sukuna just getting super angry because he can’t touch Yuuji the way he wants to touch him when he’s stuck as a blob
