Thanks for the translation gist, Kale! (+Rep if I can...)
Three months... That a bit... Insane? Well, the quests are a obvious... Which I don't mind, since that's what makes this Wedding feature intersting.
Now that we know the basics, let's hope the pre-wedding event quests goes well, as well hopefully the real wedding feature comes out in eTO. Hopefully there is no drama while at it.
