Following the events of their trip to Okinawa, Saitama University graduate students Shinya Yukimura and Ayame Himuro have failed to obtain the data necessary to scientifically prove their love for each other. Unable to replicate the exact conditions of the trip, the two stubborn scientists decide to seek help from elsewhere in the university—the Biological Sciences department.

Assisted by fellow graduate students and longtime couple Chris Floret and Suiu Fujiwara, Yukimura and Himuro begin to quantify their feelings by measuring their output of oxytocin in various romantic situations. The two scientists soon find that their feelings for each other are nothing compared to that of a mature couple. It is here that Chris poses a question to both Yukimura and Himuro: what will they do if their "affection" is proven not to be love after all?

Desperate to find a scientific rationale for the discrepancy, Yukimura puts everything on the line to prove that their "love" is real.

A very good second season anime. I will make this review as short as possible. The story continue where it left off in the last season, so nothing change much.

I also didn't focus much on the story or rather I didn't try to reason the story and just went with the flow. It's obvious that the story is crazy but my focus was elsewhere so my recommendation to those who are wanting to watch the second season is to not expect ...

Mixed Feelings
I’m going to assume that You’ve seen season 1 so I won’t repeat myself to keep this brief.

When it comes to characters almost nothing has changed. They are still one sided, cliched and poorly written. The plot is still cliché and the show as whole still lacks good writing.

From episode 1 the season doubles down on the quantity of slapstick comedy without raising its quality, at least in the beginning. The first 2 episodes are painful to watch. The show can’t go 3 minutes without a cheap joke during them.
I did have some hope for the show around the halfway mark. That’s the ...

Very disappointed from the turn of events in this season. Instead of continuing the same sort of events from season 1, this season focuses a lot on the side characters.

---Minor Spoilers Ahead---

The side characters I mean some of the developments were great like with ibarada and the other dude but the thing that really ruined and bothered me was that this season's focal point changed from the romantic subtext from season 1 to building an unnecessary harem around the Male protagonist which is just... terrible. I don't know what got into the author's head but he just turned the whole plot upside down.

The last ...
