JI just found out this news today.

Plus I watched a few videos about thatis kind of accommodation.

As a single person, I am kind of accepting of such a living condition.

Sure, other forms of similar ideasimilar ideas already exist, like shareing a house, and net-café already exists.

This is also grammatically correct, but it sounds redundant to me:

"Sure, other forms of this idea already exist, like sharing a house, and net-cafés"

I wonder willif they would have a short -term contract for a month, or shorter period of time.

Usually "would" and "could" are used when you say a phrase like "I wonder if..." and you are wondering about ideas or concepts.

You can use "will" if you are wondering about a definite event that will happen. For example "I wonder if the band will give us free t-shirts at the concert I am going to next week."

On the other hand, Hong Kong already haves this kind of accommodation.

But the environment is just…

If this is being spoken aloud, you need to indicate with body language what the environment is. Otherwise, a word must go after "just".

Because even now still a lot of people still live in such places.

So, if you really want to know the Hong Kong style.,

Jjust search the internet willto know the difference.
