[Walkthrough] Shall we date? ☆ NULL; (Story Jar) ☆ Radison

Game: NULL;
App: Story Jar 
Characters: Radison
Ending: Radison's Lover

My final affection points: 370/373 
My costs: 785 Diamonds (612 for the main story, 133 for no affection answers, 40 for a CG in Chapter 19)

NOTE 1. With this walkthrough you will be able to get the best (?) ending, I suppose. 

NOTE 2. These paid answers mean that you will not get affection points, they are free to pass - you can choose another option on the screen, but the scenes during these are more hilarious, romantic, etc. If you have some Diamonds to spare, you can buy them just for fun if you truly enjoy the story.

NOTE 3. After reading a chapter, do NOT click on Continue for Pass 1, but instead choose Home button and go to chapter's menu. There is a rare chance for you to get a Free Chance Pass and read the one for free. Or watch a video for 1 Diamond reward. I recommend doing like this after every chapter.
