Before Class

Rin sighed as Yuki came and sat on her lap.

"What's wrong Rin-Nee?"
"It's nothing Yuki-Chan."
"Failing math again Baka Rin" Len smirked
"Stop being mean to Rin-Nee, Baka Aniki!"
Len looked taken back at Yuki's words, Rin couldn't help the laugh that escaped her lips. Len regained composure throwing more insults at Rin.
"Yuuuuuuuukiiiiiiiii-Chaaaannnn!" A disgruntled Hiyama sensei could be he hard from the hallway.
"It's Hiyama sensei! I've gotta hide, don't tell him I was here Rin-Nee, Aniki."
Rin and Len watched as the 9 year old hid in the cupboard at the back of the room.
"Have you seen Yuki-Chan?" A fuming hiyama sensei asked.
Len spoke with a tone of childish innocence, "I haven't seen Ringo-Chan since I dropped her off at your class this morning."
"If you see her please tell me" hiyama sensei huffed before running out of the classroom in search of Yuki.
Crawling out of the cupboard with an angry childish expression on her face Yuki shouted "DON'T CALL ME RINGO-CHAN!" Realising how loud she shouted she ran from the room to find a new hiding place.

"Len-Kuuuun!" Shouted an obsessive Tei as she bounded towards Len. Following close behind Tei was Teto a girl with twin drill ringlets on each side of her head matching the colour of her eyes, red. Tei noticed how close Len was to Rin and glared blood red daggers at the Blond. Rin, noticing the glared backed away from Len, the white haired girl was know for her knife collection and her obsessive crush on Len. Groaning on the inside Rin couldn't help but wonder why her seat was next to Len. Tei took "her" seat behind Len (The girl who used to sit there "mysteriously" vanished first term) as their teacher walked through the door.

"Kaai-San and Kagamine-San please remain after class" Megurine-Sensei stated with a stern look.
"Yes Megurine-Sensei" Len and Rin chorused.

During Lunch Break

"Kagamine-San it has been known for a while that you are failing maths so I propose that Kaai-San be your tutor, if your score does not improve by the end of the year you will repeat the year." Megurine-Sensei's stern tone silenced all sniggers from Len and all looks of protest from Rin.

"Rin-Chan what's wrong!" Cried Miku, Lenka, Lui and Ring as soon as the blond came into view with a scowl on her face. Rin explained her problem with a grim expression.
"So every day after school you have to go to the library to study with Len?"
"Yep"
"Just the two of you?"
"Yep"
All at once the whole group burst into fits of laughter all except Rin who was glaring at her friends.
"What's so funny?" she exclaimed.
"Nothing" the group sniggered between fits of laughter.

As school ended Rin gloomily walked to the library to meet Len for her tutoring session. Pushing open the heavy mahogany doors, Rin entered with a long sigh earning her a harsh "shhhhh" from the librarian. With an apologetic look in her eye Rin hurried to a seat in the middle of the library to wait for Lens arrival. Positioning her maths textbook on the mahogany table Rin sighed softly and placed her head on her hands, closing her eyes to wait for Lens slow arrival. 7 minutes later Rin had drifted off in a light sleep.
Strolling through the hallway at a leisurely pace Len arrived at the library late. He had been distracted talking to his childhood friend Rinto that he forgot about tutoring Rin. Pushing open the doors he walked up to the table to shout at Rin for being stupid. He paused when he noticed her sleeping form and bent down to her level. He grabbed her ear and pulled her into a sitting position.
"OUCH! What was that for!" Rin exclaimed!
