Chapter 1

Every year during vacation, the dance academy takes all its students on a group trip.

The destination is a special place: an island said to improve people’s dancing skills.

They say that any senior student who visits the island, no matter how inflexible she is, comes back with an unusually graceful, feminine air.

It wasn’t until I set foot on that island myself that I finally learned the truth: the entire seven-day, seven-night trip was actually a process of “training.”

This year, I was accepted into the most famous dance academy in the city.

The academy had a rule that everyone loved to cheer for: every vacation, the dean took the dance students on a group trip, covering all our food and lodging.

This year, the trip fell to our group of freshmen during the October break.

The night before we left, I changed into the practice clothes my roommate Jessica handed me and couldn’t help staring at them thoughtfully.

The practice outfit was much thinner than what we normally wore to class, especially the fabric, which felt almost exactly like a young girl’s soft skin.

“Oh, Lily! You look like a seductive little enchantress in that outfit. Even I’m getting thirsty just looking at you!”

After saying that, Jessica grinned and pinched my waist.

Her words made me blush, so I turned toward the mirror.

The woman in the reflection had flushed cheeks, and the outfit outlined her full curves with remarkable clarity. It really did leave plenty to the imagination.

After taking off the practice outfit, I joined my roommates for their late-night gossip session.

They said the department director was actually using the trip as an excuse to give us “special training.”

The citywide dance competition was held every two years, and this year’s event would take place after the October break, while our destination was the academy’s legendary “Dance Island.”

One of my roommates said the island was incredibly magical: every senior student who visited came back with a more flexible waist, making difficult dance movements feel effortless.

At that, Jessica pushed out her impressive chest. “Really? Can it make my weapons even more powerful too?”

The dorm erupted in laughter.

After comparing our respective “weapons,” we washed up and went to bed.

I had barely lain down when I felt the bed above me begin to shake, accompanied every so often by a breathy sound that was both pained and delighted.

Seriously, Jessica was acting up again!

I had originally wanted to ask what Jessica did every night, but at that moment, my mind was filled with the island my roommates had mentioned.

I had known about the dance academy’s vacation trip for a long time.

The winner of the previous competition had been my older sister.

She had only managed to take her dancing to the next level after receiving the dean’s professional training on the island.

So I spent the entire night in excitement.

What kind of special training could turn my stiff-limbed sister into the first-place winner of a dance competition?

The next day, as soon as I followed the group onto the bus, I heard many students looking me over in amazement.

Their attention made me feel confident and pleased, so I knew exactly what had caught their interest.

My sister and I had both inherited our mother’s beautiful figure, especially our chests, which were striking and full, but I was even more developed than either of them.

Even the department director, who had been counting heads, stopped when he saw me and praised me.

“This student is practically overflowing with dancing talent. I’ll make sure to train you properly during the trip!”

At his words, I began excitedly calculating in my head.

After being trained, would I be able to enter the dance competition too?

If I entered the competition, perhaps I could finally learn the secret surrounding my sister from two years ago!

With those expectations in my heart, I began the journey.

Inside the bus, the stuffy air made everyone complain nonstop.

Even though I sat beside the window, I could feel my skirt sticking damply to my skin.

I stopped caring about my appearance and pulled open my neckline to let myself cool down.

Just as I began to feel a little better, someone suddenly blew across my chest.
