That was one epic troll by the mangaka, leading us to believe that Nanoha was going to make a New Year's resolution of a serious nature about trying to get serious about school or get her thoughts about her future settled so she and Chidori can be more secure in their plans. Then NOPE! Forget that! Resolve to do what's REALLY important!
It's been a slow built, but these two have definitely grown a lot as a couple. I hope we'll get to see quite a bit more of that! It does feel like we're heading into the final stretch though.
They really took their new year resolutions to heart ! Chidori being more forward is a nice change of pace for her, she really does need to be more honest about what she wants in general.
