I liked Sumi initially, but I am insulted that her character is becoming "just another younger girl that chases him as he chase Mizuhara". I wanted her to have a bit more to her character other than "quiet and trying to not be quiet" before trying for the MC. Fortunately for the author, I can find it in my magnanimous personality to forgive him/her for this slight and only reduce my score from 10/10 best girl to 9/10 best girl because her character art and facial expressions blew my pants off this chapter.
