I really like this but the sisters were pretty goddamn annoying. Especially the parts where they were like "boys are all stupid" meanwhile they were the ones who kept getting in the way with their stupid advice. Mind you I still love this and think its the author's best work, but I would've preferred if they didn't spend a good portion of each chapter on the sisters and instead on the more adorable main couple.
That first chapter really clouded the rest of the story. But its stupid because it feels like it didn't have all that much bearing on the rest of the story and it felt out of character for the bottom.
