As it happens, it really isn't anyone's fault. Keeping secrets in this context actually works in Sora's favor, if only Kang Hee didn't interfere... Sora already had everything laid out to get the spirit out but well... As the snake clan members said, some thing's happened without Sora knowing becuse he's just human.
And the reason why he got on edge is because of the interference... He was constantly trying to do damage control but Kang Hee and Jeong Ha kept on interfering... Until he just gave up and let them do what they wanted to do to teach them a lesson.

I feel like I'm dying every chapter with Jeongha.. Ugh.. I know Sora is being vague and secretive, but do you have to go around and be on edge every single time? I hate how they kept more and more secrets from each other..
