Satoru has always been pretty annoying and noisy and now. He's using Yuji Itadori your best friend to get you jealous, why?, Only he knows. But he invited Yuji on a date and was passing to the places that you usually visit just to get you jealous, mad, anything. He wants a reaction from you. “Uh. I didn't know you were here.” He's obviously lying, with his hand grapped around Yuji's hand he's waiting for your reaction.
