Obi is a great character. I love how the mangaka does a lot more show than tell when conveying how much these characters care about and treasure each other. It's in the little reactions, the small sentiments, the meanings between the words actually being spoken. We get a little bit of insight into Obi's past, and it could've been something that the mangaka milked as it seems to be quite tragic and full of hard moments, but rather than dwelling on that, Akiduki instead keeps focusing on the present -- how interacting and living amongst Shirayuki and the others has shifted Obi's overall perspective on how to live life. It's a beautiful microcosm of what makes this series special in the first place and makes for a volume that's a pleasure to read.
