how to unlock hiden achievement ..... i gain the first four how to unlock hiden achievement ,but the last one .....how to unlock??

it says nuditiy but it's unclear what it is

So far this game is fun but it would be more entertaining if you could pick the new paint and stuff when renovating the coffee shop. that would also be a great way to unlock new/longer dialogues with the character you pick

ONE OF KIA'S SPRITES HAS A DIFFERENT SHADE OF LIPSTICK THEN THE REST AND IT IS KILLING ME

When you do the Mikhail route and click on the CG, after the first click it says "Image 2 of 2 locked." Any idea what that image is or if it even exists?
