I'm not seeing Drama nor Harem tags. So I can hope that there isn't going to be bullshit with the other 6 dragons vying for her.
Though, I do hope we can see her go back with her new husband to rub that little shit sister's smirk right off her dumb twin-tailed face. No doubt that witchy bitch will drop the prince in a heart beat should a hansom dragon show itself and practically throw herself upon him in hopes she'll steal him from her protagonist elder sister. Only to be horribly scared by the poison, maiming her for life as ugly as she is on the inside.
Did it come across that I hate that character archetype? I wasn't sure if that was apparent or not.
