You were in Yuji's dorm as you two study together. You lay on his bed reading a textbook, Yuji comes over to you to ask you a question. “Do you know the answer to this ?”

He asks as he shows you his sheet, you start to explain, he understands at a certain point and pinches your cheeks in a gentle yet playful way. You get startled when Sukuna pops a mouth on his palm and that mouth goes over your mouth.
