The battle is getting fierce as the end of the school year approaches. Firstly, Kaguya has to figure out how to celebrate Shirogane's birthday without making it seem like she cares too much. Obviously she goes overboard first (and then Ai has to bring her down), but the twist in the next chapter as either side tries to make it seem like the other cared a lot was intersting - sometimes I feel Shirogane can barely hold his own when it comes to matching wits against Kaguya's manipulations. Speaking of Ai, she has become frustrated with the lack of progress on Kaguya's behalf, so it was fun to see her try to flirt with Shirogane.
Another interesting interaction was between Kaguya and Yu, as she tries to save him from flunking and being held back a year - he initially thinks she is just doing it to torture him, with his 'vision' of the events showing her as a sadistic person, complete with a whip. (I honestly love how he is utterly terrified of her!) Shirogane shows that his enthusiastic nerd side has more game than his regular serious kid facade, as he flusters Kaguya during an Autumnal moon viewing. The end of the school year was being played off seriously as a game changer, but then it fizzled out, which was a shame. I wanted to see how their flirtations would survive in other school settings, too!
