I just like seeing these sorts of moments, myself. Helps reinforce that they are happy together. And I’m a fan of ‘lovey-dovey’ in general.
Would like to see the other characters get some attention, too, though. Maybe Miki gets a boyfriend. She has an amusing banter with Hattori, though I dunno whether they’d work out as anything more than frenemies.
We did get to see actual non-gyaru Saotome, beyond just a photo from the past. I prefer her without the fake tan and bleached hair, but I kinda agree with Yamato, too- it feels wrong.
