I'm not in a ReiYoshino mood at the moment. So here is some SeiShimako!
Promise
Shimako gave a sad sigh. Soon Sei would be leaving, in fact she was graduating today. She had been counting down the days til now wishing time could just stop. When the first woke up this morning she reliezed how pointless of a dream that was. So here Shimako sat dreading the graduation ceremony that was drawing nearer. "Oi!" the teen turned to see her onee-sama. "Gokigenyou, onee-sama." Shimako said as Sei sat down next to her. The third year calmly replied ",Yo." Shimako glanced at her grande soeur and sadly turned away. "What's wrong?" the first year didn't answer, didn't Sei already know what was wrong? "Nothing," Shimako replied.
She felt sei put her arm around her affectionately ",I don't see why you're so worked up about me leaving." Shimako rested her head on Sei's chest ",It'll be lonely without you onee-sama." "No it won't," Sei said calmly ",You'll see. Spring will come and you'll move on." Shimako felt tears cascade down her cheeks as tried to get up. "You don't want me to leave and yet here you are trying to runaway?" Sei said as she embraced Shimako to prevent the younger girl from leaving.
When she was sure Shimako wouldn't run off Sei let go of her. She smiled at the first year who was slightly confused. "Onee-sama?" Shimako asked staring at her grande soeur ",Why are-" She had been cut off by her onee-sama. Shimako was in a state of pure bliss during the short kiss. When they parted Sei smiled at her imoto's flustered face ",That's a parting gift."Shimako looked saddened when she heard the word parting. "And this," Sei kissed the first year again ",is my promise to see you soon."
The end. It's so short...I guess that's what I get for writing it out of boredom without an actual plan. You can praise, insult, or whatever you please in your reviews. So please review.
