I know that Take's pretty mean to Umeko, but page 15 had me in stiches because that level of inexplicable rage is so sibling-specific. I relate so hard
The plot thickens!!! I love how these characters are all kind of blunt in their own ways so the transparent communication between them is really refreshing.
I have such strong respect for the MC. Hope things look up for her though. She's remaining level-headed and rational, but she's definitely detached and resigned to her situation.
