I really loved the first chapter. It's cute about how protective he is without the plot indicating any incestuous relationship or complex (though I don't mind). In fact,I decided to buy the licensed one in my country because I can't find any continuation.
I have to say I'm a bit disappointed. First, this oneshot manga usually put the title of the series the same as the chapter only, and the rest of the stories will be like a collection of oneshots. I'm prepared of that. Second guess, the next chapters will still focus on the same setting, character, and universe. This is what I actually wanted. I was hoping to see that Tamako might have more development with that male classmates, and more appearance of her protective but meanie brother.
But, half of the book was spent on chapter 1, and to my surprise, chapter 2 took about 3/5 of the book until the last page. And what was the second chapter all about? It's the story of how the girl (who slept with him in ch1) met Takumi for the first time, finding out about his real jerk personality, and fallen in love with him.
aww, not like I hate this manga directly just because of that, but I really really still hope it'll be more to the siblings relationship. lol
