Okay, just to clear things up cause I don't really understand myself: Sometime between Mumei receiving the news she was going to die and going to the sanatorium, Mumei returned to Konoha. She was assigned as a temporary shinobi of Gai's team and that's why she is so attached to them. I didn't put that in Mumei-sama yet because, well, I don't know why. Anyways, now you know.
Chapter 6.
After a few questions of how she was and her past events at the sanatorium, the team eventually left for training. "Goodbye Mumei-chan!" Shouted Lee skipping out the door. Gai bowed and Tenten waved. Neji started to leave and while at the door, turned around with a concerned face on. Mumei saw this and held up and peace sign and winked. Neji nodded and left the room.
Mumei looked down at her book again but this time, after a few minutes, she closed it and put the elastic strap on.
Another few minutes went by, she pushed the book off the side of her bed and it landed in her backpack.
Realizing she was already wearing her grass-green shirt and dark green long skirt, she jumped into her shoes and opened the window. She grabbed her backpack and swung-out of the window landing in a squatting position.
She hopped through one of the first story windows and ran down the hallways to the front entrance. She narrowly escaped the sight of the nurse at the front desk and ran through the glass doorway.
Looking back to see if no one saw her she kept running until somebody grabbed her wrists. She looked in front of her. It was Neji.
"Going some where, Mumei-chan?" said Neji with a blank face on, looking over her head for he was taller than her.
"No. Just taking a walk. If you'll excuse me…." She said trying to go past him to his left. Neji kept a hold on her wrists and she couldn't move anymore.
"You're not supposed to leave your room and you know that, Mumei-chan!" Neji said getting serious and bringing his face down to hers.
"I need to go back to the village! Did you not just hear that I would get in big trouble if I didn't! I came here to defend Konoha and I did. I don't even have Yari with me!" she said begging for him to even let go the slightest. Sure she could easily escape from his grip but she'd be drowned in guilt before she could make it too far. After all, this was some form of Neji caring for her.
He took one of her arms and pulled her along side him, they walked up a story and back into Mumei's room without a word. He let go of Mumei and pushed her to her bed and she laid down with the face of a six-year-old after losing an argument, crossing her arms.
Her face lightened up a little and she looked at Neji.
"You cared for Konoha, so we care for you." Neji said as he slid back behind the door and shut it.
"Was that some form of 'thank you' or something?" Mumei asked her self as she went back into sleep.
