"I can't believe this!" Rin shouted, slamming the door to her room that she shared with her brother. Hearing the noise, Len looked up from his homework and stared at his sister. What happened?

"Something wrong?" he asked. Rin groaned and sat down at her desk, not wanting to talk to anyone. Len watched her, curious. He'd never seen his sister this upset. Clearly something had happened.

"Rin, tell me what's wrong," he persisted, standing up and walking over to her. Rin shook her head and ignored him. Suddenly, the door opened, making the twins look over to see who was there. Rin glared and Len raised an eyebrow.

"Um, do you need something, Miku?" Len asked, wondering why the tealette wasn't doing anything but stand there and stare. On closer inspection, Len concluded she was staring at Rin.

"Oh no, Lenny, she doesn't need a single thing from me!" Rin shouted angrily. Len flinched at the sudden volume of her voice. "In fact, nobody needs me for anything! I don't see why I'm even here anymore!" Rin stormed out of the room, knocking Miku back into the wall on her way out. Len stared in shock at the scene that had just played out. He was tempted to hep Miku up, but he was pretty certain that she was the one who got his sister upset in the first place. He glared at her.

"What is going on?" he demanded. "Tell me, right now. I swear, if I find out you lied, I'll burn your secret leek stash!" Miku yelped and held her arms in the air in defeat.

"Okay okay, just don't touch my precious babies!" Miku exclaimed. "Rin and I are working on a project together, and I got mad at her because I thought she was messing everything up, so I told her that I didn't need her help, so she went to go help Luka cook, and she added salt instead of sugar to the cookies, so Luka said the same thing, and then she went to go watch a movie with Kaito, but...well, I think you get the point..." Miku frowned. "I came in here to apologize to her. It was me who messed it up, she didn't do anything wrong." Len frowned. He needed to show his sister that someone still needed her. And he was determined to do so.

Len grabbed his homework and ran into the living room where he saw Rin sitting on the couch, twiddling her thumbs. "Perfect," he said to himself.

"Hey Rin!" he said, a little too excitedly. Rin looked up and frowned, wanting to be alone.

"What?" she spat out. Len frowned, hurt by her rudeness. He made his way over to the couch, a little less excited.

"I need your help," he said. "I can't figure out how to solve these equations. Can you show me?" He smiled at her hopefully. Rin frowned and crossed her arms.

"I'm not good at helping people. All I'll do is screw everything up," she said, and left. Len sighed. This was going to be hard.
