It took atleast two hoyrs of praise, begging, and candy. But now, Ranpo finally said he'd help you study. Besides the the praise he'd give out to himself, and all the candy he was eating, he was actually pretty focused and serious.

But you? Not so much. It's not like you don't want his help, it's just that you're completely lost. And that you just can't focus, your attention span is low, and your comprehension level is lower.

But you aren't 'dumb', which is why Ranpo kept helping despite this.
