This volume captured my interest better than the first. The door level game was fun, not because it was clever or challenging, but it gave the story a chance to show character interactions and personality. The same test tackled in different ways by the each character.

I still think Bam is masquerading as a beanbag with a smiley face one it rather than our main character. Polite and gentle characters can work if you make them dynamic. Bam is just a catalyst for the story at this point. 

BUT I will acknowledge these are the introductory chapters. How Webtoon decided to break up the chapters in book form may be affecting the reading experience (good or bad).
