I like how Yamada and Ichikawa help each other make big steps in their relationship, like going on an after-school movie date. It's not just one of them pursuing the other – they meet in the middle. In the Valentine's Day arc, Yamada had been working up the courage to give Ichikawa the cupcake, but she only managed to do it after he gave her the Meltykiss chocolates. Similarly here – Yamada gave Ichikawa the movie tickets and he stepped in to invite her on the date.
