Sister's Bestfriend

Chapter 1

TZUYU'S POV

It's 6 am. Another day of work. I sometimes think of getting someone to work for everything I need to do in my company, but I can't risk having a stranger take over the company. 

It's my father's company, and now that he's gone, I need to take care of everything he left. 

"Tzuyu! Get up! Mom is calling you already!" I heard Nayeon, my older sister. 

I just hummed and get up from my bed. 

I made sure to fix my bed before getting in the shower. 

As usual, I wore black pants, black socks, black shiny shoes, and white t-shirt. 

It's like my uniform already. I hate thinking of what to wear everyday, so I usually just change the color of my suit which I rarely wear. 

Once I went downstairs, I found Nayeon in the living room doing pilates while watching a drama on the TV. 

"Can I watch some news?" I asked her. 

"No..." She answered. 

"You stink..." I said and went in the kitchen. 

"I don't! It's you who you can smell!" Nayeon shouted. 

I was about to yell back at her, but Mom gave me my coffee which is very fragrant and it made me relax immediately. 

"My baby boy is so handsome!" Mom said which I always hear everyday. 

"Thanks, Mom..." I said and sipped my coffee while reading an article on my phone. 

I finished my cup of coffee in just a few minutes and went back in my room to grab my things before going to work.

"Tzuyah!" Nayeon called me before I could even grab my car keys. 

"What?" I asked. 

"Can I borrow your car later at night?" She asked. 

"No... I'll drive you anywhere you want... just don't drive it..." I said. 

I have many cars, most of them are sports car, and I can't let Nayeon drive even my cheapest car because she's a shitty driver.

I once made a mistake of letting her borrow my car, and the front and back bumper was severely damaged when she returned home. 

"Come on, Tzu! I'll just go to my friend's house..." She pleaded. 

"No... I'll drive you... I'll be back before dinner." I said and kissed my mother's cheek. 

"I have no kiss?" Nayeon asked. 

I unwillingly kissed her cheeks and left for work. 

I met Chaeyoung and Dahyun in the office as we have a project to work on today. 

It's a very stressful day for me, and I am so drained when I returned back home. 

"You're eating like a pig..." Nayeon said while we're eating dinner. 

"I'm hungry... I'll just shower after eating and I'll drive you..." I said. 

"I'll go to Momo's house." She said and I nodded. 

Momo noona is her bestfriend ever since she's in college. We treat her as our sibling already for they are so close to each other. And Momo is sleeping in our house more than their own house. 

After a few minutes, I finished my meal. I also finished taking a shower, and I waited for her for 2 hours to finish getting ready. 

"Let's go!" Nayeon said and we both went to my Bugatti 16C Galibie. 

While driving across the city, there was a slight traffic on the way, and I decided to take another road to get to our destination faster. 

"I'm going to sleep in Momo's house, so you can leave once we arrive." She said. 

I nodded and felt relieved that I don't have to wait for hours and be called at 2 am just to pick her up. 

"Isn't that Sana?" She asked while I'm making a right turn. 

I slowed down and looked at who she's staring at. 

"It's her..." I said.

"Let's take her with us... she's also going to Momo's house..." She said and I stopped the car on the side, putting it on hazard. 

Nayeon went out of the car and took Sana noona with her. 

"Let's go!" Nayeon said when she and Sana noona got in the backseat. 

"You already asked me a favor, then you made me look like a driver... how nice of you..." I said making her laugh hysterically. 

"You're laughing like a witch... I'd never date you if I'm not your brother..." I said which offended her. 

"You're so snobby and cold, I'll also never date you..." She said. 

Sana noona had to stop the both of us from arguing which was always the case when we're with her. 

Our friends already know our love and hate sibling relationship, so they're used to us bickering all the time. 

It's not that I hate her, but she's just annoying. 

Once we arrived at Momo Noona's house, I helped them carry their bags inside and left after greeting Momo Noona. 

"No kiss?!" Nayeon asked making me sigh. 

"Call me if anything happens." I said and unwillingly kissed her cheeks before leaving.

Being Nayeon's brother is tiring. She's always asking for attention, and if I don't laugh at her jokes, it's like I made a unforgivable sin to her. 

When I arrived back home, Mom was about to close all the lights, and lock the doors. Thankfully, I'm just on time and didn't need to sleep outside or get in a hotel. 

The next morning, I woke up at 6. As usual, I went to work and worked until lunch because it's Saturday. And during Saturdays, I only work until lunch. 

"Tzuyah!" Nayeon said when I answered her call. 

"What?" I asked. 

"Pick me up at Momo's..." She said. 

"Fine... but you have to treat me lunch... I'm hungry..." I said. 

"Fine... just get here fast..." She said. 

I hung up and picked her up. 

"Let's drop Sana at her house." Nayeon said and I could only nod because it's I don't have any choice. 

"Mina is hilarious... she really went drunk last night." Sana noona said. 

"Having a broken heart is that hard when you really love someone dearly." Nayeon said. 

"Tzuyah... you shouldn't break hearts like Mina's ex... women needs to be loved, not played with." Sana noona said. 

"Wow... a piece of advice from someone who hates commitments..." Nayeon teased Sana noona. 

"That's why I'm not seeing serious guys... so I won't hurt them." Sana noona said. 

I just listened to their stories and when we arrived at Sana noona's house, I helped her get her things inside and left afterwards. 

"I want hotpot..." I told Nayeon. 

"I don't have my wallet, though..." She said. 

I sighed and gave her my card. 

We ate our lunch and went home after listening to her nonsense stories. 

I never called her "noona" because I don't feel like calling her. She's also acting like she's younger than me, so it's not necessary. 

She also doesn't care, so it's clear. 

Even if we have 5 years age gap, our bond when we were kids was so strong. 

Everything changed when... I changed.
