It's not that I don't trust Yu Nai, but she is an only child and lacks experience in this area.

"And besides, you're a department head, so you should be the most logical one, right?" I wondered aloud.

Finishing my sentence, I threw the manual I was holding to the ground and grabbed a cloth to help Yu Nai reach some spots she couldn't reach.

"On another note, don't you realize that I'm half a head taller than you now?" I said, smirking.

Smack!

Before I could even turn around, a not-so-light slap landed on my buttocks, almost making me fall onto the blackboard.

Yu Nai was greatly displeased by my sudden comparison of heights, after all, she is slightly older than me. But in terms of height, there is indeed a noticeable difference between us now, much more apparent compared to our elementary school years.

However, Yu Nai is not the type to nitpick and quickly got back to work, giving me orders.

"Stop chatting, go get my chair, the one by the back window..."

"No need, here it is!" I said, turning my head and shaking the new cloth in my hand, indicating that I can also help.

The atmosphere in the activity room immediately became livelier. The two of us broke the long silence and started conversing.

It's been so many years since then. We have been attending the same institution since elementary school, although we weren't always in the same class, luckily, we were eventually placed in the same class.

"It's great that I'm your boss again this time. You better be careful not to give me any ammunition!" Yu Nai threatened with a tone filled with authority.

"Heh, it seems like my grades have always been better than yours. If you can pass one subject better than me, then maybe there's a chance." I sarcastically replied.

"Hahaha, you really haven't changed at all, just like before. Only you, Juxi, can brush off everything and not care! But speaking of that, my math grades are really bad. If I fail the exam again this time... ah, my mom will definitely make me attend that devil training camp... hehe, Juxi..."

As she spoke, Yu Nai winked at me and kept leaning towards me.

I knew her intention. In general, there was only one possibility in situations like this: "Cheating on the exam? No, no, no. Although I helped you copy last semester, you know the consequences. We ended up with a zero in math!"

I had no room for negotiation, not even using her charm would work.

Seeing that I was unmoved, Yu Nai started acting cute again.

"Juxi..."

"It's not happening. You know, if I fail one subject, my summer vacation is doomed. Besides, my summer is already packed. In addition to daily studying, I have to help the seafood restaurant owner recruit staff. There's a lot to do!"

"Huh? Juxi, are you so sure that you'll pass the exam?"

"Yes, only someone with a bias towards math teachers like you would fail, right?"

"Well..."

"Sigh..."

In the end, I couldn't argue with her. After all, we've been childhood friends, and I can always lend a helping hand with positive energy.

So, I came up with a solution, "Let's give it a last-minute effort! You're not that bad at math, as long as you work hard now, passing the exam will be easy."
