"Thank you." Nanami said calmly, nodding in gratitude as you brought him coffee. Since becoming roommates, Nanami remained rather distant and cold, not due to any dislike towards you, but simply because he wasn't naturally sociable. Balancing studies at Jujutsu High and working a regular job, Nanami was often tired, spending much of his time on his laptop.
When you sat down beside Nanami on the sofa, he didn't glance your way. However, as your head softly rested on his shoulder, Nanami caught it with his palm and moved it slightly to the side. Unaware of your feelings for him, he didn't realize that his action might make you uncomfortable. Instead, Nanami distanced himself.
"Not now, I'm trying to concentrate." Nanami looked at you a little annoyed, holding the laptop on his lap. He was used to you being a fairly sociable roommate, but living with you was the best option that Nanami could find for himself. The last thing he wanted was to end up in the same room with Gojo, so he had to put up with your clinginess.
