This is a great concept, but I feel the pacing was too poor, and it should've had more dialogue or something to stretch it out. It just feels too quick. Very charming, though.
YES! ABSOLUTELY LOVE THIS! Someone else had the same thoughts I had on what it would be like if Josuke was babysitting Jolyne! I wonder what it would be like if she met Hayato or that rock-paper-scissors kid too (since they'd be closer in age to her at the time). ^^
