I think it's probably because of their goals. They might have thought,"I'll ask her out when this is all done."And maybe because they thought Amore can be a distraction to their work.Or maybe the boys have so much pride they think they're just gonna end up being dumped.Well, it wouldn't hurt to try right? How about te guys? What do te think? Now I wish Arakawa-san is Leggere this. She doesn't know how many people would like to see Ed and Winry o Roy and Riza kiss.I wish there was a psychologist in the series,so that way Winry o Riza won't have a hard time thinking,"What do men want from women?" o Roy o Edward would think,"How am I supposed to impress her?"
