I see what's happening here; Tonikaku Cawaii does have a plot, but instead of like most stories with a plot, they don't skip over the interstitial parts, where between the "important" bits Nasa and Tsukasa still live their lives and do random newlywed stuff. Like, Nasa had a weird exposition dream, but he doesn't IMMEDIATELY go resolve that--the next few hours/days/whatever are still just living his normal life.
