"Hey Len, it's time for you to wake up now." Rin's voice filled the silence in her twin brother's room. He stirred from his sleep and slowly opened his eyes before turning his head to face the female. "Alright..." He responded groggily as he stood up and rubbed the sleep from his eyes. He watched as the girl hesitated in his doorway and couldn't help but feel guilty. She no longer acted like herself in front of him. Ever since he'd distanced himself from her as a child, their close relationship seemed as if it had never existed. "Do you need something?" He finally questioned the other blonde, who only shook her head 'no' in response and walked out, closing his door behind her.

Rin let out a long sigh as she walked downstairs and into the kitchen where both of her parents, Leon and Lily, were seated for breakfast. "Good morning, Rin." Her mother chirped up, looking away from the newspaper sprawled out on the table in front of her. "Ah, Rin, 'morning." Her father responded as well, as he smiled up at her. She nodded to the two of them and ran a finger through her shoulder-length, golden locks of hair and released a sigh, "I'm going to leave early, okay?" Was her response as she slipped her school shoes on at the front door and exited the kitchen silently. "I wonder what's wrong with her…" Lily murmured after an awkward silence filled the room. "You know how 16 year olds can be, dear." Leon teased as he took a sip of coffee from the mug in front of him. "I don't know, Leon… Don't you remember how close Rin and Len used to be when they were younger? They were inseparable! Now we can barely get them to stay in the same room together…" Lily couldn't hide the worry in her voice as she closed her newspaper and stared at her husband across the table. Surely he'd noticed the sudden difference in their children's relationship as well. "Their relationship was getting too close, Lily. It's good that their like this now and I don't want to hear another word about it."

Len, whom was dressed and spying on them from the staircase, stared down at his shoes. It was his fault, after all, that he and his sister were complete strangers now. But he only did it so that she wouldn't get hurt. They'd fallen in love with each other at the young age of 14 and their close relationship caused them to be the main subject at their school. He and Rin were constantly teased about being so close and he could remember the look of horror on his parent's faces when the two of them walked in on Rin and Len exchanging a kiss before bed.

"I'm going now, too." He suddenly announced as he practically darted out the front door to find his sister.
