Guys, I just finished the second volume and man... This flashbackk may seem stupid at first, but it is very important to introduce many things, I don't know how I could judge the author for putting it in the beginning of the story when I read it the first timme . I don't even know if I would care about Luke's friends if it wasn't for this flashback, and there are also several other things that are presented... You did well here, author-san!
