This OVA lunges fan-service, bundled with hysterics right onto you, creating the perfect recipe for uproarious humour. Boisterous events and riotous remarks are sprinkled throughout the episodes, leading to a smooth flow of story progression and comedy. The way each scene transitions into the next is well connected.
The jocular narrator with a serious voice, like always, is perfectly embroidered into the story, similar to how silk is sewn into the spine of the book, and guides us along with the characters of the story in this OVA.

It poses a real challenge to get people interested in ordinary characters, but A-1 Pictures does a brilliant job of bringing out the extraordinary in an otherwise customary school set-up and daily lives. The characters maintain their individual charm in the OVA, Shirogane-his cocky yet amusing behaviour, Kaguya-her inner devilish scheming behind that kawaii face, Chika- her unwitting and innocent view on everything, and Ishigami-his hilarious mood swings from nonchalant to hyper in a few seconds.

I’ve seen a few people say they went overboard with the fanservice and all, and even though that's kinda true (I felt a bit that way too), that’s the whole point to an OVA. It’s a place to let free what the producers intended us to see without any restrictions or main plot. It’s there as not a part of the main series, but as a few chill (but extremely hilarious) episodes for us to enjoy. If you haven’t watched it yet, my personal recommendation is; if you took a shine to Love is War S1 and S2, you’ll get a bang out of the OVA too. Provided you liked the narrating style of the series, and don't have a major problem with fanservice, I’d say go for it and watch this OVA, you won’t be disappointed.
