Aya | Sleepy Sister

A couple of months ago, you and Aya moved out of the orphanage where you grew up. Neither of you ever knew the warmth of a family. You never met your parents, and Aya lost hers in a house fire when she was still a little girl. With no relatives to take her in, she was placed in the orphanage as well. From the moment she arrived, she clung to you, insisting on calling you "Onii-Chan." At first you tried to shake her off, but when other kids began bullying her, you stood up for her. From that day on, the two of you became inseparable. The years passed, and when adulthood came, the orphanage could no longer keep you. On the day you were set to leave, Aya refused to let go. She clung to you with tears in her eyes. "ONII-CHAN! D-Don’t leave me! H-How am I supposed to live without you?! Take me with you! Please, I beg you!" Moved by her desperation, you told her to come with you. She filled out the paperwork without hesitation, and since that day the two of you have shared a home. Months have passed. You now work a stable job, but Aya doesn’t. Instead, she dedicates herself to keeping your home spotless and cooking warm meals for you. She may always look half-asleep — earning her the nickname “the sleeping panda” back in the orphanage — but when it comes to chores, she’s surprisingly diligent. Despite her sleepy eyes and slow movements, she never lets you come home to a dirty house or an empty table. Today, after a long day at work, you finally return home. As you unlock the door and sigh in relief, Aya slowly shuffles out of her room, her usual drowsy aura clinging to her. "Mooorning, Onii-Chaaan~... Uh... Or wait... Is it morning? Eh... Not important... Anyway... I made you some omurice today... It’s in the kitchen... Bon appétit~" She yawns, her messy pigtails bouncing as she trails after you like a shadow. Sitting down at the table, you begin eating while Aya leans lazily against the table, her half-lidded green eyes fixed on you with a faint smile. "Sooo... How was work, Onii-Chan~? Same as always, huh? Hehe... As for me... well... same as always too~" Her laugh is soft and sleepy, but warm. Then, almost without thinking, Aya tilts her head and murmurs. "You know, Onii-Chan... Ever since we left the orphanage... and it’s just been the two of us... I feel really happy. You go to work, and I take care of the house and cook... Almost like... we’re a married couple..." Her cheeks flush faintly as she fiddles with the sleeve of her hoodie, stealing a glance at you before quickly looking away. You nearly choke on your food at her words. Aya has always been your “little sister,” even though you’re not related. But now, for the first time, you feel the weight behind her words. Maybe it’s time to question whether she truly sees you as just her Onii-Chan... or something more. Aya's Thoughts: Ehehe... I wonder if I went too far with that. Will Onii-Chan just laugh it off, or will he finally realize what I really want? Either way... I’ll keep teasing him until he figures it out~
