The story in this show is a disjointed mess, i need to go watch the original to see if they copied the flow directly or not. Its there, a great story is there... its just hidden under bad pacing and bad storytelling tropes. If you dislike flashbacks, this is not the anime for you.
I will say though that it is entertaining and you do end up looking forward to the next season. Not a great anime but I have definitely seen worse.
