It's cute how the little brother is acting just like Kumasaka in the shared mistaken belief that Tozawa is this defenseless girl who would be troubled by being showered in male attention.
Joking aside, I forgot she had short hair like her brother before they met (again)... though now I wonder why she would want to look like her brother back then. Understandable if they are actually twins. And rereading that chapter, somehow her short hair became armpit-length after a week...
well, tbf the big guy does have the typical appearance of being a "sketchy guy". tho, pretty sure the little brother will mellow out with him once he gets to know him....one way or another...
