12: Who initiates the New Year’s kiss?
TBH I kinda see Winry initiating most of the things in their relationship. Ed is just so damn awkward. She’d probably stand right in front of him when the clock tells them it’s midnight and ask: “are you gonna kiss me?” and he’d be like “whaa-aa-t???” and she’d be like “fine. I guess I just have to do this myself then.” and she’d take his face between her hands and give him a big smooch. Not super romantic, I know, but these two don’t do anything in the “normal” romantic way (which doesn’t mean they can’t be sweet!). Edit: after they become a thing officially, Ed gets more confident and he usually initiates it.
14: Would your OTP take a walk together in the snow?
I don’t see why not! The only problem there is is the automail which gets super cold in cold weathers but they’d probably change it to the winter model when it gets that cool. But Ed still gets excited about snow whenever they get it so he would drag Winry from her workshop and maybe even challenge her to a snowball fight or something.
