Great chapter. It's nice seeing these two as a couple and no longer as just enemies and then kinda sorta friends lol. We're now actually seeing how their dynamic has changed now that they're dating. For instance, Tsubaki isn't as easily angered by Kiritsu and does make the effort to recognize that Kiritsu being uptight is who he is and being more tolerant of that despite clearly wanting to do lewd things with him. And then there's Kiritsu himself, who is clearly trying to better articulate how appreciative he is of Tsubaki.
Of course, the two of them expressing genuine affection for one another comes off awkward because they're incredibly inept when it comes to romance lmao. But that has its charm as they navigate their romantic relationship.
