just re-read the summary & some of the comments, & i remembered why i didn't consider reading it — i'm in my early 20s so it just grosses me out when i read age gaps, unlike when i was a teen ☠ but i'm assuming she doesn't end up w the sensei everyone is raving abt (& based on my comment u responded to), she'll hopefully pick a classmate
