if someone can read this...

Keys2ykingdom actually made a good explanation about soundproof rooms.

"Technically the best way for a room to be soundproofed is to be use several noise cancelling materials and to vacuum seal the room to make it air-tight. However as far as I know, noise canceling materials aren't 100%. Plus, vacuum sealing requires a motor - which is definitely not silent - as well as taking time - something Asami and Akihito didn't have. So at best, Asami and Akihito are in a room that cancels most sound."

So it could very much be that room. Someone on tumblr made a diagram of where the panels take place.

That looks very much like Asami's room. And it makes for better suspense to draw them searching right outside the room they are hiding in (especially since this is shown right after they are).

So yeah, they actually could very likely be (and probably are) in the panic room.

i wish they are not in the panic room I want more suspens. well we will be sure in two months TT.TT

Hey hey, if anyone like werewolf story, you guys can check out my friend's werewolf story (not a manga) on Wattpad (a platform for stories, can be download as a app or read from the website). Really sorry if it's annoying but if you could check it out, it will be really great. Thank you for your time.

Between the shoe closet and the kitchen, the long corridor is a pantry. Between the bathroom and the laudry (and powder) room, the corridor is a Japanese inner garden.

Lightasus thanks a lot !

How is it not suspenseful if they are? Asami says they can't find the room but Akihto managed to before, and there's apparently three entrances to it, so there's a good chance they could (I feel that Asami's guards will arrive backup right before they do though).

Asami has a Japanese inner garden and we haven't seen it yet?! How scandalous! (╯°Д °)╯╧╧

I know right? When I first read it, I was like: whaat? I want to see it so bad >.<
Sensei wrote "as it's the penthouse", so maybe many Japanese penthouses have those? Anyway, it's a "Tsubo Niwa", if anyone wants to check it out.

we know already about a panic room,it will be better if there is another myster in that house, for exemple i love to see asami's closet shoes, inner garden and why not aother secret passage.

Is it possible that they're in the small space between the secret room and asami's room? Cause they seem squished together and asami said not to make a sound. Then they show the intruders looking through asami's room.

@ohwam when i saw this page http://www.mangago.me/read-manga/you_re_my_loveprize_in_viewfinder/mh/v08/c051/19/ this idea crossed my mind, why they are so tightened AS sardines and just behind the door, i mean the panic room is wide and spacious???

When you're in a bunker during a natural disaster, the bunker is usually spacious enough, yet people will still hover together. It's for protection and reassurance. Asami can protect him better if he's closer to him, should they find the entrance. They're close to the door because the sounds will be muffled and they wanted to be able to hear them when they get close to be prepared.
