More Than A Big Sister (Yandere Sasuke x big sister Oc)

Chapter 4: His highest priority

Sasuke POV

It’s been 2 years now. I am now 9 years old and she is 14.
Yuma-nee was on a mission 2 weeks ago and she promised to come home today! I feel exciting, can’t wait for her arrival. She always kept her promises! If she said she will return home today, she will! It was lonely without her at home. Everyone in the village respects her because she is now the well known ninja as ‘The Mortal Lighting’ and the greatest shinobi in the world! I always look up to her and admire her strength.

I heard that her speed is similar to the Fourth Hokage but way faster than him. When I grow up, I want to be like her! Stronger! Faster! But… feeling jealous that a lot of kids like my age started to call her ‘Onee-chan’ and always getting her attention. I frown at the thought of it. Damn it! She’s not yours! She’s mine! Mine only! I hate it when they clinging to her all the time after school.

Tch…

Even that dope (Naruto) beaming at her and invited her eating together at Ramen shop.

Flashback

After school, we were walking across the street side by side and feeling nervous because she was holding my hand as everyone watching us with soft smile. I could heard them whispers.

“Look at that.”

“How cute.”

“Of course they are! They’re siblings!”

The word ‘siblings’ made my chest hurts as if a knife stubbed it and pain. I don’t know why but… ‘I don’t like it…’ My thought snapped as we stopped walking, looking up to way she was stopping until I saw a silver haired man approach us and waved. I tilted my head in confuse but squint.

Tugging her hand to caught her attention to me, “Ne, ne, who is that?”

“This is my friend, Kakashi.” She introduced him to me.

“Nice to meet you.” He gave me a close eye smile even his face was covered.

“Hn.”

I simply replied before turned my head away from him. Yuma-nee chuckled nervously at my antic before she began having conversation with that guy. While watching them talking happily, I felt like I don’t like this guy. What’s with him? The way he talked to her… I don’t like it. He might take her away from me! Just like everyone else! Feeling my blood boiled in anger, I variously pulled her hand and drugged her away from him.

“A-Ah?! S-Sasuke?! Oh! I’m sorry Kakashi but I have to go now!” She exclaimed to him.

“S-Sure. See you later!”

After satisfied the long distance away from him, she spoke up to me with clueless yet curious expression, “Is something wrong, Sasuke? You don’t look happy about something.”

I pouted, “Of course I don’t! I don’t like him…” I murmured at the last sentence.

She chuckled, ruffles my hair with a smile, “Are you jealous?”

“….”

“Aww… my little Sasuke is jealous~ How cute~” She squealed, pinching my cheeks playfully.

“S-Stop it!” I exclaims, embarrassed.

She treats me like a little brother… but I don’t want her to treat me as a kid… I want more than that. That was until we encountered Naruto at our way heading passed the shops. When the blonde saw her, he raised his arm up and waved grinning like an idiot. “Yuma-nee!! Do you want to join me eat ramen together?!”
