• The characters in both the anime is very similar we have a girl who is into otaku culture spends majority of her's time playing video games then we have a good looking guy who isn't intrested in having any romantic relationship. Now imagine if both of this characters fall for each other yaa that's what happened in both of this anime. • Both focus lots on comidy but there is also some drama moment. • Neither of them have any ecchi scene.
Both force the romantically uninterested heroines into a parody of romance clichés. They also share the same sort of "awkward but sweet" feel between characters whenever comedic situations happen. Leads are also obsessed with video games, which has made it hard for them to find any romance before the plot of the shows.
