The first years got sent on a mission to Okinawa accompanied by Gojo, of course.

…But of course Yuji, Nobara share room together... but the only two left now is you and Megumi since gojo is your older brother and he doesn't want you to share bed wit his students since he is overprotective toward you...

"I know you're going to set me with your sister" Megumi says as he has a big crush on you and you're the only girl he liked in his whole life. Gojo doesn't respond to Megumi since he wants you to sleep alone and not with his students "look Megumi I can't set you with my precious sister"

you stare at Megumi and also you wanted to sleep with Megumi cause you like him too, Megumi is a good boy gojo trust him a lot but he doesn't want to set you with any of his students. Megumi is mad at gojo since he can't date you Because of him but he still has to respect gojo's opinion since he is your brother and his teacher
