I sure do take on a lot of side-stories, don't I?

A/N: I don't own the series.

"Senpai!" Nagatoro called as she opened the door to the art club room. For the past half year she had been visiting the room on a daily basis. The reason? She loved getting a reaction out of the lonely boy who always seemed to be in there. Things had gotten interesting from there. More than once she had modelled for his sketches and slowly "bonded" with him.

Normally when she came in she would find him sitting at an easel sketching another boring still life. This time, however, he was sprawled out face-first on the couch she had brought in earlier in their relationship of sorts.

"N-Nagatoro?" he sputtered as he lifted his head up. He wore the same worried face that almost always came with her presence, but there was an overlapping sleepiness to it today. In typical Nagatoro fashion, a plan immediately formed in her mind, and her face shifted into a devilish, slightly psychopathic grin.

"What's wrong Senpai?" she mockingly asked with an emphasis on "senpai". "Did you stay up too late watching your perverted animes?" She got right up in his face with the second question. Senpai's face was already turning red, and she reveled in his panic.

"I-I don't watch perverted stuff. I just stayed up too late studying," he tried to explain.

"Sure. You're really gross Senpai. Gross, gross, gross." The whole time she did a little poking around his chest, joyfully watching his startled reactions. Instead of getting overly flustered like he normally did, he just rolled over so he was laying face first on the couch again. A small groan escaped his lips, but that simply wouldn't be enough teasing for Nagatoro.

A weight dropped onto his back, and he didn't need to look to see what the source was.

"Nagatoro?" he asked. He knew she was probably grinning again.

"What's the matter Senpai? Can't get a girl like me off your back?" she rhetorically asked. She had learned from experience that her victim lacked muscle to the point of being a literal human twig. "Or are you secretly enjoying having me on top of you? I bet you are, because you're so lewd," she stated. It was a shame she couldn't see his face; she would have to do something about that soon.

"Come on Nagatoro. Please," he requested, still with a tired tone. It was going to be in vain, but it was still at least worth a try.

"Nah. Besides, a virgin like you should enjoy having my butt on your back." To follow up, she laid back and placed herself so her back was against his. A quiet noise of surprise came from the boy beneath her, who was trying to turn around so he could get leverage.

"Oh, trying to feel around?" she asked with a wicked grin. Her canine flashed just before the boy managed to get on his side and caused the girl to slide off him.

"Senpai, you made me fall," Nagatoro whined. She had only fallen behind him, so she had been more pressed into back of the couch rather than actually pushed off of him.

"Sorry," he offered, which was followed by a large yawn. Nagatoro slapped him surprisingly gently on the back of the head then climbed over him and off the couch.

"Are you? Or were you just trying to get away from me?" she questioned. "Or maybe you were getting hard and didn't like it pushing into the cushions." Another grin crossed her face, which was a stark contrast to her victim's face, which held a lazy yet embarrassed expression.

"I, I'm not h-hard. I just wanted to get you off," he stuttered, only to realize his mistake when the words left his lips. "Off of me! I wanted to get you off of me!" he clarified, which was followed with another yawn.

"Hmmm. Sure, that's what you meant," the tanned girl replied in a nonbelieving voice. She knew that's exactly what he meant, but this was too good of an opportunity to pas up on. "I'll bet that's where your lewd mind goes at night," she mocked, adding a light flick to his forehead from emphasis.

"No it doesn't," he shot back. His eyelids drooped for a second, then shot back open, only to droop again.

"Getting sweepy?" He hardly managed a response as his lack of sleep finally caught up to him. Nagatoro watched as his eyes closed and did not reopen.

"Ahh, what am I supposed to do now?" she complained. She couldn't get him all embarrassed if he was asleep, and he probably wouldn't wake up before the next class period. Her friends, who had also taken joy in teasing him, would be more than willing to jump at the chance to have him all to themselves. They had already tried to shave his head and put him on a leash in her absence before, not to mention the time Gamo-chan had forced him to feel a pastry disguised as her boob.

She paced around the room for a few minutes as ideas came and went. She could sketch him, but there wasn't any fun in that. Plus, she would probably get it from her friends for acting like him. She could draw on his face and take photos.

Yeah! That's what she could do! She went around the room and collected the best markers before crouching in front of the sleeping boy. Too bad he wasn't awake; this would be a prime chance to poke him for looking down her skirt.

She pinned the thought in her mind to try another time and popped the cap off a dark pink marker. She carefully placed her hand on his cheek to support the drawing when he flinched. She froze in hopes that she wouldn't wake him before she could start, but his face continued to move until she hoped he stayed asleep for another reason.

He had turned enough to cause her had to cup his cheek. The marker dropped from her hand and rolled away as she took in exactly what was happening.

Out of curiosity she decided to push it further and gently ran her thumb up and down a few times. A contented exhale whooshed from his mouth.

"Senpai, are you really enjoying this?" she asked. There came no reply, either in words or actions. No flush came to his face, and his breathing stayed as rhythmic as ever.

"Senpai?" she muttered. Still no response. "He really was up late," she mumbled to herself, not quite realizing she had kept her hand against his face. When it finally hit her she drew her hand back. A blush similar to those she usually got out of Senpai filled her cheeks as she thanked the deities that no one was around to see this.

As her senpai continued to sleep, Nagatoro noted the unusually calm expression he wore. Sure, there were times when she wasn't tormenting him that he seemed at ease, but those times usually led to more bullying from her or her friends.

It was odd to see him so relaxed for a change. Even when he was sketching still lives there was an aura of concentration to him. She had found herself either entranced by his antics or unexpected acts of kindness or taken off guard when he accidentally got a feel of her more than once, but this was...different. The closest experience to this was when she invited herself over and took care of him when he had that cold, but he was also delirious that day, so it was hard to actually count that one.

The sleeping teen shifted a little and propped a hand beneath his cheek as a pillow. In her own twisted way of thinking, the action gave her yet another idea. She raised herself and gently grabbed Senpai's head. She lifted it just enough to squeeze herself beneath him. She carefully lowered his head until he was resting on her lap. While the images of him getting all embarrassed when he woke up flashed through her mind, they were quickly replaced by the thoughts of how comfortable the position was. His head wasn't so heavy that it was unbearable, and his long, soft hair felt weird on her legs, but not really in a particularly bad way.

"Argh, what am I thinking!" she quietly scolded herself. She was the one who was supposed to make him overthink these situations, but here she was doing just that herself. The boy's head shifted a little. Nagatoro quieted down and held her breath. After half a minute of nothing happening, she assumed he was still sleeping.

Boredom began to set in, so she whipped her phone from her pocket and scrolled through her social media, unconscious of her free hand burying itself in Senpai's hair.

It wasn't until she finally looked down that she realized. Shock and confusion ran through her system for a moment. To make it worse, she found herself liking the feeling of having his hair between her fingers. She softly ran her fingers up and down his scalp, occasionally gently scratching his head. A few contented sighs escaped his lips, and Nagatoro found herself more invested in repeating the simple motions than she had expected. A distracted glance at her phone revealed that there was only ten minutes before the next class would start.

"Senpai! Senpai, wake up!" she urged. She rocked him back and forth and pounded on his back. After enough effort the boy began to stir. He sat up and yawned with a stretch. Nagatoro quickly and silently repositioned herself to keep Senpai from finding out what position the two had been in.

"Feeling better sweepyhead?" the girl asked in her typical teasing attitude. Senpai sighed at her greeting, completely unaware of what had transgressed.

"Yeah, a little. What's wrong? Is the next class about to start?" he asked. A look at the clock told him he was right and he got up to collect his things. "Uh...see you, Nagatoro," he offered with a wave before leaving the room.

She, on the other hand, wasn't as fast to head to class. She was too busy wondering why she had chickened out at the last moment. When she finally opened the door to leave the room she was welcomed by Gamo-chan, Sakura, and Yoshi waiting for her. "Hey. 'Sup?" she asked nonchalantly, to which the three just giggled. A feeling of dread overcame her.

"I dunno, what's up with you two?" Gamo asked as she showed Nagatoro a picture she had managed to sneak of the two. Nagatoro reached for the phone with the intention to delete the picture, but Yoshi and Sakura held her back.

"How long have you guys been here?" Nagatoro demanded once she finally gave up an getting the phone.

"Long enough," Sakura replied. She ran off to class, leaving Nagatoro with Gamo and Yoshi.

"Good luck," Gamo offered before departing, which Yoshi copied.

"Long enough?" Nagatoro asked herself as she walked to her class.

What was that supposed to mean?

A/N: This was a little one-shot I wanted to try. I binge read the series and decided to give this a try. It's admittedly a little awkward, but I hope you liked it.
