This is exactly what you'd expect from an OVA of the first season. If you like the first season, then there's no reason you shouldn't also like this cute little bonus episode. Surprisingly however there is more interaction between the various side characters and our two protagonists than probably the entirety of the first season combined. Also, surprisingly we get a lot of time from the POV of Takagi which is very unusual. We only got to see small glimpses of Takagi's POV in the first season whereas in this OVA her POV was significantly more if not the majority of the runtime. We get to seein real time how she schemes up ways of teasing Nishikata but in reality, these teasing schemes are all just an elaborate excuse to be get close to him and spend time with him. It's all very cute and sweet as you've come to expect by now.
