Hyehwa adult play with a hidden basement ticket booth: Nine Theater

In short

Nine Theater is a small Daehak-ro theater in Jongno, Seoul, a short walk from Hyehwa Station exits 1 and 2, currently staging the 19+ adult play 'Suspicious PT Shop.' The writer saw the Saturday 6pm show with her partner and had to go down to the basement and find the door marked 'OPEN' on the right before the ticket booth appeared. With 80 unfiltered minutes and audience participation events, Nine Theater's Suspicious PT Shop makes an offbeat date for couples and married pairs.

My partner and I decided to have an outdoor date for the first time in a while~! We picked a play in Hyehwa 👀 It was called 'Suspicious PT Shop' 👀💪🏻

Let me spoil it a little upfront... 1. Real adult performers appear 2. It claims to be the raunchiest show in Korea. Just from that, can you imagine how intense it might be?

It wasn't just 19+ — by my standards it was more like 39+. I really had to rethink my assumption that 'how intense could it be'...

How to walk to Nine Theater from Hyehwa Station, and showtimes

The theater entrance already looked suspicious from the outside (lol). There's a bromide poster standing out front that looks exactly like a PT gym ad 😜

It's a short walk from Hyehwa Station exit 1 or exit 2! Perfect to stop by after strolling through Marronnier Park or Naksan Park 👍

Showtimes run Mon, Thu, Fri at 7pm / Sat at 3pm and 6pm / Sun at 3pm, with a biweekly 6pm slot! Tickets can be booked through Naver, Coupang, and Nol Ticket 🎫

On the way down, there are various posters promoting Suspicious PT Shop plastered on the walls! It felt like something huge was going to happen once we got down there... lol

Can't find the ticket booth? Look for the 'OPEN' door on the right

What confused me a bit at Nine Theater was the ticket booth. They said booking opens an hour before the show, but there was nothing there!! Turns out there was a door on the right marked OPEN. You just open that door and walk straight in 👀

The right side of the entrance was decorated like a cute little hair salon 💇🏻‍♀️ Turns out 'Suspicious PT Shop' is a sequel to 'Suspicious Hair Salon'!

Once you pass through what feels like an alleyway and go further inside!

You come out into a space decorated like a real PT gym 🏋🏻‍♀️ There were all kinds of exercise equipment set up! I was really curious how they'd make this concept 19+ lol

Tickets and the waiting area at Nine Theater

A small, easy-to-carry ticket! It had the reservation name, date, and seat number 😌

There was also a spot for tea (water was available too 💧) and the AC was blasting, so even if you have a lot of time before the show, you can relax comfortably. I really liked that too 🥺

Saturday 6pm show: doors open at 5:40pm

This was the entrance for the show. We watched the Saturday 6pm show, and admission started at 5:40pm haha. We hurried in around 5:50 and eagerly checked out the stage ✨

Entrance into the performance hall

The stage was decorated just like a PT gym too! The show ran about 80 minutes total! You know how important comfortable seating is for shows like this, right! I was able to watch comfortably the whole time, over an hour long ☺️

Also... before the show starts, an actor comes out and interacts with the audience. If you participate actively, you might get a 19+ style gift(?), and that moment naturally gets woven into the show's content later(?) — there's some really fun stuff hidden in there! It might be a spoiler, so I'll save it 😂😂

How explicit is Suspicious PT Shop?

And here's my review after watching...

  • It's really raunchy. Genuinely raunchy.
  • Full nudity happens. I was like, is this even allowed?
  • Wow, everyone's bodies were seriously insane wow (P)
  • Explicit scenes play out with zero filtering

Setting the story aside, I think you all get the idea of just how intense this is 🙊

As for the story, it starts with women running a new PT gym, and then the male actors go through some very special personal training 🍿 I'll stop here since it might be a spoiler‼️ lol

Photo time with the cast after the show

After the play ends, you get a photo time with the cast! Suspicious PT Shop has a total of 5 actors, and every single one of them kept the show engaging without a dull moment... genuinely impressive ㅠ.ㅠ

Especially on the day I saw it, one foreign actress showed off incredibly attractive muscles... I genuinely gasped out loud. And it wasn't just the muscles, other things too... (self-censored) lol

Looking for a 19+ play in Hyehwa? I'd recommend Suspicious PT Shop as a decent(?) watch with friends, partners, or spouses~! 👍
