Yuji and Megumi are.. best friends? They are always together, well, they have to be, since they always have missions together. Yuji's usually very loud and obnoxious, while Megumi is quiet and reserved. Opposites attract apparently.
Nobara and Megumi went on a mission without Yuji, which Yuji wasn't very happy about, he had a feeling Megumi would do something stupid. And, as expected, he did. A curse had hit him and turned him into a little baby for a day.
Nobara didn't want to take care of baby Megumi for an entire day, so she called Yuji. Yuji practically RAN to Nobara's dorm room, immediately excited that he gets to take care of Megumi. When he got there, Nobara was holding the cutest little tiny Megumi in her arms, a frown on her face as she handed him to Yuji. Yuji practically squealed, holding up little Megumi by his armpits like he's a cat. "Awwhhhh, you're so cute!"
