This is my first ever K-ON fanfiction. This story takes place during the girls senior year.

The Mystery Texter.

Chapter 1.

The school bells ring and a male teacher walks into the class.

"Good morning class." He said and puts books down on the desk.

"Good morning Mr Harold." Said the class, except for one. Ritsu Tainaka was busy on her phone texting quite fast. Before she got to class, she silenced her phone so no one would hear her phone go off during class. After all, they weren't allowed to have their phones in class, with the exception of homeroom. Yui saw Ritsu on her phone and just watched her friend text quickly. Yui was wondering who was Ritsu texting? And why is she texting a lot more than usual?

"I wonder who Ristu is texting? I got to find out, and tell the others." Yui thought to herself.

Mio walks in late and went to her seat. "Sorry I'm late sir."

"That's alright. Now is everyone here?" The teacher asked and looked at role and looks back at the students. "Good. Now proceed to return to page 3 in your handouts." The class gets their papers out and Ritsu was texting again. Yui glances back at Ritsu and saw her on her phone again.

"There she goes again. texting in class. She hasn't even pulled out her packet yet." Yui thought to herself. Later, the class bell rings and the time skips to later in the day. The girls enter the light music club and Yui quickly takes them into the storage room.

"What are you doing Yui?" Mio asked.

"Listen girls, in class today I saw Ritsu texting." Yui said.

"So? What about that? We all text you know." Mio said.

"Well she's doing it a lot. Which might explain she's not here yet." Yui said.

"I think I hear the door opening." Mugi said.

"It's Ritsu." Azusa said. They peek and see Ritsu place her bag down on the couch and sits down at the table and pulled out her phone. She looks around and starts texting.

"See. What did I tell you?"

"Well Yui, should we jump out at her?" Mio asked.

"I think we should sneak up and see who she is texting." Azusa said.

"Right." Mugi nodded and the 4 girls slowly open the door and come out quietly and sneak to Ritsu from behind. They get closer and are behind Ritsu, trying to see who she is texting. Ritsu surprisingly does not know her friends are right behind her, looking over her shoulders and head. Ritsu closes her phone and the girls eyes become wider. Realizing that Ritsu must feel a presence behind her. Ritsu then yawns and stretches her arms out. Yui, Mio, Mugi and Azusa quickly back away but Azusa trips. Ritsu turns around to see her 4 friends.

"What are girls doing? Trying to scare me or something?" She asked.

"Yea! We were just trying to scare you. It's not like we were trying to look at your phone or nothing." Yui said nervously.

"Yui!" Mio covers her mouth. "What she meant to say is...we were planning on surprising you. That's why we weren't in here when you came in. Right Mugi?"

"Yup."

"You know how Yui is." Azusa said while getting up and dusting herself off.

"Well you didn't scare me so looks like your fun act failed. So how about we get some tea and snacks going Mugi?"

"Right on it." Mugi smiled and soon all 5 girls were sitting down eating cake and having tea.

"It's too bad Sawako couldn't be with us today." Yui said sadly.

"Well Yui, she has got a ton of papers to grade." Mio said. Ritsu opens her phone and texts her mystery texter. None of the girls notice.

"I can't let them know who I'm texting. If I do, they would so get jealous of me and might quit the club." Ritsu thought to herself. She puts her phone in her pocket and finishes the snacks.

"So are we gonna practice today?" Azusa asked.

"I know, plus Mio has new lyrics and we really want to hear them!" Yui shouted.

"Quiet down Yui. You're gonna bother the other clubs." Mio said annoyed. "Also...the new lyrics sound corny."

"I'm sure they don't sound corny. I'm sure they sound fantastic." Mugi said.

"What do you think Ritsu?" Yui asked as all the girls looked at her.

"What? Oh umm...yea...they're gonna sound great. Hehehehe."

"Is something wrong Ricchan?" Yui asked, getting closer to her.

"No. Why do you ask?"

"You seem to be out of place." Yui answered.

"I'm fine. Can we just practice please?"

After the girls finish practing two songs, Ritsu wasn't having an energetic feel she gives on the drums. She really wanted to text that someone that the others didn't know about.

"Ritsu, something is wrong isn't?" Mio asked.

"No. I'm fine."

"Then why do you look unhappy?" Yui asked.

"If you're feeling sick, just tell us." Azusa said.

"I need a break. Sorry." Ritsu said and went into the girls room and pulled her phone out and started texting. She gives a sigh of relief. She then smiles at the text this person sent to her.

"She's been gone for like 10 minutes. What is she doing in there?" Mio asked.

"Maybe is she sick. Azunyan? Would you mind go checking on her." Yui asked.

"Sure thing." Azusa said and went into the restroom. "Ritsu senpai? Are you in here?"

"What?"

"Ummm we are kind of worried about you. Are you feeling sick or anything?"

"No I'm fine."

"Well are you coming back for practice?"

"Yes. Just give me a minute."

"Okay. I'll let the others know." Azusa leaves.

"Sheesh. Can't a girl like me get some privacy." Ritsu said and checked her phone and blushes and smiled.

"Ritsu said she's fine and to give her a minute. She'll be back shortly." Azusa reported the information to the rest of the group.

"If she's not back by 5 minutes, I'm gonna pull her out." Mio said. Ritsu returns. "Or not."

"I'm back. So who's ready for more practice!?"

"There's the energetic feeling." Mugi said.

"I am so ready!" Yui said and jumped around.

"Alright, alright, alright...let's get into position...this time we are going to try to match up a tune to Mio's new lyrics. Now the lyrics do seem happy. So we should go for a happy tune."

"Alright. I think we got this." Azusa said.

"This should be easy!" Yui exclaimed.

"I think I should start off loud and proud and work my way to soft and quiet to the end of the song. What do you think?" Ritsu asked.

"I think that's a great idea. Just not too loud or you'll drown us all out." Mio said.

"I think I should go first for a couple of seconds and then Mio can come in and then Azusa and Yui and Ritsu can join me for the beginning with a soft and quiet drum beat and then to loud and proud when all of us jump in. Sound good?" Mugi suggested. Yui's face lit up like a light bulb, after hearing that idea.

"That sounds awesome! The song shall be called: Happy Tea Day!" Yui exclaimed. "What do you think?"

"I like it. Fits well for the lyrics that Mio wrote." Ritsu said.

"Thank you Ritsu." Mio smiled.

"Let's not waste any time and get this new song rolling!" Ritsu said and went to her drums and the band started playing. The song lasted for a good 3 minutes until the big soft finish from all members dies down. The girls were really happy with the result and Yui stated she thinks this is their best song yet. Ritsu couldn't wait to tell her 'texter' this wonderful news.
