The typical route for OVA episodes like this is beach episode or hot spring. This just felt like another regular episode of the show, and not even particularly special one. The hijinks with the maid uniform in the first part was kind of funny, and then a lot of the last part is just them talking about a cat. If this had been a normal episode of the show I wouldn't have thought much but it being it's own separate thing I'm going to rate it a bit lower than the main show. It felt tacked on and didn't really serve a purpose other thanto be a bonus for people who just really really wanted more I guess. 7/10
