Episode 5 is so far the most normal episode, and that is saying a lot. Boys antics, the coming of summer, a trip to the beach, and another step in Urabe's and Tsubaki's relationship due to a strange tan line.
One of the interesting aspect of the episode was the beginning part where the boy took a sneak peek at the girls in their swimsuits. It similar to other animes where the boys catch a glance of their female classmates figures but it isn't over the top or anything outrageous. It more innocent since they are just curious. The one note that sticks out from this is the way Ueno and Tsubaki were only interested in seeing their Girlfriends, showing that they have little care about the other girls and only focus on the ones they truly care about, despite being slightly perverted about it.
Next comes Urabe's and Tsubaki's first date. Things have been pretty hard on Tsubaki when he and Urabe hardly see each other in the summer, only to meet up for some drool exchanges. However, Tsubaki's suggestion for a date definitely breaks the ice between the two's lack of time being spent with each other, where Urabe agrees to it after she comes back from her fathers house. It possible that Oka's influence may had a impact on Urabe decision to agree with Tsubaki idea for a date since she didn't agree to anything before.
Now that the date is all set, Tsubaki is hype to see his girlfriend in a nice bikini. What he didn't expect was the nice tan Urabe got from her trip to her father. This leads on to Tsubaki appreciating Urabe exotic looks while getting a spacial moment with seeing her scissor shape tan like. This makes it spacial since he the one who only knows that Urabe holds in scissors in that position. At the end of their date, Urabe taste how Tsubaki feels about the tan line and makeing her understand how he feels and his needs.
Nothing too spacial about this episode compare to the others, but this helps cements the small amounts of development that the two are going through.
next episode: past love comes back to the picture.
