Yesterday, I was really happy that this game become indexed and appear on the site!
The traffic was instantly raised, and the number of download keep increasing.

But I realized the game was tagged as containing sensitive content by the moderator.

Technically, it's not wrong. I put a warning on the game's description that said "this game contains unsettling theme that some people might find disturbing".
But ... note the word "unsettling" and "disturbing". It's not a "common" words to describe something that turns you on.
So, before I ruin someone's expectation about what they're going to see on the game, let me clear things up.

This game has NO graphic nudity or explicit sexual content.

Honestly, I don't mind this game being on the NSFW section, but at least I want to know the exact reasoning behind their decision of marking this game as NSFW.
So I tried to contact the support staff to get some explanation. At the time when this post is being written, I'm still waiting for their reply.

My apologize for the people who thought this is an actual adult (read: sexual) dating sim game ... (˚ ˃̣̣̥᷄⌓˂̣̣̥᷅ ) 
I should've give this explanation sooner ...

But anyway, if you're curious about what the warning actually means, you can play the game yourself! But of course, player discretion is advised.
I hope you enjoy your time with Eva!

Edit : The NSFW tag has been lifted by the support staff!
