He had to admit, she was an amazing girl, human or not. She had incredible will power. He couldn't help but start to like her, but they were teacher and student. Plus, she was only there to learn how to fight. Then she would be gone and he would be back to his normal routines again. He kept thinking of her fighting against the arrancars. Being outnumbered and then being struck down and…No! Stop it, Hisagi! He mentally scolded himself. She was only his concern until she was taught. Then it wouldn't matter what happened to her. He sighed. Who was he fooling? He was starting to care about her. But that didn't matter. Their relationship was strictly student-teacher. No matter what would happen.

He let her look around his studio and he explained some of the things they did there. She really seemed genuinely interested. He sighed. How he wished they could actually have a chance together, but she probably didn't feel the same way. Either way, he knew that all he could do for now was teach her.

The walk back to the 6th division barracks was quiet, well, until they arrived at the barracks and he heard a little girl run out yelling Tatsuki's name.

"Kagamine!" Tatsuki said cheerfully. "I thought I told you to stay inside until I got home."

"But you are home." She said.

"Lieutenant Shuuhei, this is Kagamine. One of the servant girls of the Kuchiki family. I guess you could say I took care of her last night and now she loves me to pieces."

"L…Lieutenant?…" Kagamine said, jumping out of Tatsuki's arms to bow on the ground. He was used to them bowing, but not so used to anyone paying attention to them.

"Tatsuki," he said. "Kagamine is a servant. Why would you care about her?"

"Because. Kagamine just lost her brother and I didn't want her to be alone while she's mourning. Oh yeah, we're going to light some incense for him tonight. Would you like to come along?" She asked him. He was so confused…but intrigued by her interest in the little girl. He couldn't very well turn her down. After all, he did say he'd be with her in the evenings and there was nothing wrong with lighting some incense.

"Hm. Sure." He agreed. "We can skip tonight's training for the lighting of the incense, but be ready to work tomorrow."

"Hai!" She smiled. "Thank you, Lieutenant. This really means a lot."

"Kagamine," she jumped up when the Lieutenant said her name. "Get up."

"Hai…" she stood up and stood close to Tatsuki, holding the red hakama.

"Lieutenant," Tatsuki said. "Well…I was wandering…how…did you get those scars?"

"That's a story better saved for another time," he turned his back to her, not wanting her to see the hurt on his face.

"Is something wrong?" She put a hand on his shoulder.

"No. It's just a long story and I'd rather wait until a more private time to share it with you. That's all." He turned to look at her again, placing a hand on her face momentarily and then pulling it away. Why would I do that?… "Sorry." He sighed again. Tatsuki looked at him confused for a moment. There was so much in this world that was the same and yet so much that was different. She felt feelings here that she never felt back home, and she knew that one of the causes was standing right in front of her. Shuuhei Hisagi, Lieutenant of the 13 Court Guard Squads, and the man that she knew was making her fall in love with him.

"Shuuhei…" she looked him in the eyes and without reason, without hesitation, he pulled her close and kissed her, surprising her and Kagamine, who was watching with wide eyes at Tatsuki's side. Tatsuki looked at him when he broke off the kiss. "Lieutenant, this isn't right…" She turned away and went to run when he grabbed her wrist gently, silently begging her to stay.

"I'm sorry…I know you're a human and you'll be going back to your world but…"

"You think that's what this is about? Shuuhei, look, you are the nicest guy I have ever met and I admit that I'm starting to love you, but I have so many things to concentrate on and I don't need this to get in my way. I'm sorry, but I can't have any distractions."

"What about Kagamine? Isn't she a distraction?" He made her turn to face him. "Stop making excuses and tell me the truth. Please." He looked at her pleadingly. She had said that she loved him so what was stopping them?

"Shuuhei please…" She didn't want to hurt him, she really didn't. So why couldn't she just tell him the real reason? The reason she couldn't love him, she shouldn't. "I do love you, Shuuhei…but there's something you need to know." She looked up at him, bracing to tell him the whole truth. "Can we go somewhere more private?" She looked down at Kagamine. "Go wait for me in my room." Kagamine bowed and ran off as Shuuhei led her down the streets until they got to his barracks.

"We can talk in here." He let her go in first and he followed right after. "Now, what is so secret?"

"I used to love someone before you."
