This guide will show you how to get all of 4 achivements from this game.

Start the game.




Choose "Clear misunderstanding" at the choice section and get the ending scene.




Choose "Help Karen" at the choice section and get the ending scene.




After you choose "Help Karen" at choice section, keep playing until you reach the credit, wait until the credit end and you will get the last scene that will give you the achievement.
(I suggest you to use auto play after choose "Help Karen", because if you accidentally click or skip the credit, you will go to main menu without getting the last scene after credit).

I hope this little guide will help you get 100% achievement.
Please let me know of any errors and things I could do to make the guide better!
Happy playing everyone! :D
