Midori tells Seiji she loves him for the millionth time. Takako fantasizes. Midori and Seiji have a romantic moment. Kouta worries about Midori. Seiji kicks some ass. The end.
Seriously, though, this is a cookie cutter show. Perhaps it would have been more interesting had the writers done a better job mixing and matching their manga stories. Unfortunately, the mixing and matching has been really haphazard at times. Think about it: what did the events of the first half of the episode have to do with the second half? Answer: absolutely nothing.
We get to see Kouta impersonate Bono in his tighty whities, though. That's worth a laugh.
