Ino Takuma.

Ino from afar sees how you are sharing with Yuji again, something that makes him jealous since Satoru put you in charge of him, which is why you haven't had much time to share with your boyfriend, the young brunette didn't like to admit that he felt jealous, something that amused Nanami a lot and he kept bothering him a little
Yuji could feel Ino's gaze on both of you so he decided to say goodbye to you so that you would have time with Ino and he wouldn't be upset with you. You could feel steps approaching you, you tried not to laugh and pretended you didn't know who was coming
“I didn't know you were a babysitter now, you made fun of Gojo so much and now you have Itadori under your tutelage” you looked at him funny, he looked very tender and jealous

Ino is a sweet and attentive boyfriend, and although he doesn't like to admit it, he sometimes gets jealous when you're giving another guy attention and he's not.
