Haikyuu Series: Ignore my salty middle blocker crush

Chapter 10: Tsukki have to gain Kuroo's trust

TSUKKI'S POV
It's Saturday so I'm here at Y/n's apartment to talk to her brother personally, I'm so nervous right now because Kuroko-san looking at me like I'm his prey right now
"u-uh.. Kuroo-san? There's something I want to tell you" I said
"what is it?" he ask coldly
"I'm sorry for everything I did to Y/n in the past, I don't meant to do it, you knew me I'm salty but I will do everything you want me to do, I will do anything for Y/n" I said
"Anything huh? Well... I want you to love my sister and protect her, that's all" he said

I just nodded
"And one more thing, if you hurt my sister's feelings again I will k-ll you without hesitation" he said in his murderer tone

I gulped
"I won't do it again I promise" I shuttering
"Good" he said

He look at me like he want to m-rdering me, oh my god
"onichan? Tsukki? The lunch is ready" Y/n said
"Okay sis thank you" Kuroo-san said

He turn his head back to me with a very very serious look so I gulp
"You're going to eat with us" he said
"no it's okay I'll just go now" I said
"no You're going to eat with us whether you like it or not, because Y/n cooked for us, don't break your promise Tsukishima Kei" Kuroo-san said in his serious tone
"okay I'll eat with you guys" I shivering
"Good" he said

Kuroo-san and I went to the kitchen
"no you're sitting here beside me" Kuroo said

So I sit beside Kuroo and we eat

SKIP
As we finished eating
" Tsukki you will wash the dishes" Kuroo said
" onichan no, I'll do it" Y/n said
" no my sweet little sister, Tsukki will wash the dishes for you and besides he promise" Kuroo said
"That's right Y/n I'll do the dishes for you" I said as I smiled
"Okay? If you say so, Tsukki" she said

I just nodded, I clean the table, I went to the sink with dirty dishes and wash them all.
" Are you sure you don't need help? Tsukki?" Y/n ask
"Yes I'll manage but thanks babe" I replied
"what did you just call my sister huh? Babe?! What?!" Kuroo ask angrily
"onichan no" Y/n tried to calm him down

Oh shxt I'm dead now
"uh.... Babe? Why? Is there something wrong with it?" I ask
"wow! Just wow! You're so straightforward Tsukki but I won't let you have my little sister that easily, you have to prove yourself to me and our parents first before we let you have my sister" Kuroo said
" I understand that Kuroo-san, I'll prove myself to you and to your parents that I deserve Y/n's love and don't worry I won't break my promise to you" I said confidently
"hmm, let's see, I'll make you suffer first" Kuroo said
"onichan no! That's enough!" Y/n said
"It's okay babe, I'll be fine, I promise" I said as I smiled
"see? Sis, don't worry I won't let your precious Tsukki tired, eventually" Kuroo said

Y/n slapped Kuroo's biceps, Kuroo just laugh
"I hate you onichan" Y/n said
" I love you too my sweet little sister" Kuroo said as he laugh

"but seriously I'm doing this for you because that's my job as your big brother" Kuroo said
"onichan, you're making me cry so bad" Y/n said as her tears flows down
"ssshhh don't cry okay? It's hurts seeing you cry, I can't afford to see you cry, you're so precious to me because I love you so much" Kuroo said

They hugged as I watch them
