While I originally started this manga thinking it was cute, I've grown increasingly dissatisfied with each chapter. The short version is;
The author has this "Tell, don't show" mindset where instead of letting readers infer things from the interactions, he instead has to put "He's a delinquent who's awkward with women and she's a high school girl who looks like a child" 20 times a chapter.
The long version:
We're constantly told that "the protagonist is a delinquent who is awkward around women" but only the latter half has any impact on the story. Every page, "He's a delinquent" is thrown in somewhere but he never ACTS like a delinquent; he just feels like a shy, sensitive teen boy. I see a delinquent as more violent, antisocial, using anger to hide embarassment, and so forth, but we never SEE any typical delinquent behavior from him. I'm admittedly pretty biased and have a soft spot for delinquent protagonists who contrast their rugged, rude behavior with sensitive or other gentle hobbies or desires/hopes. Honestly, if the author completely dropped the "he's a delinquent" aspect of the story and just made him a "normal guy who's awkward with women" I probably wouldn't have minded it so much. That, and the fact that author feels obligated to declare "He's delinquent who's awkward with women and she's a high school girl who looks like a child" every goddamn page honestly is really annoying.
Also please delete the other version, I messed up and posted the same comment twice instead of editing.
