First of all, I wanted to say this that this is a fantastic otome game I ever played. I played Yuzuru's route first and I got a good ending which is a heartbreaking. Anyway, from 1-5 stars, I give 5 stars. :) Well done!!
Like the idea but not the app Game is a good time killer but the app needs improvement. In particular, if you mark with the pencil then exit and reopen the app, the pencil marks are converted to final marks. A button to see the achievements is convenient. Another thing is to introduce a button to remove all the pencil marks at once. Superb!
