A romance between a straight-laced newscaster and eccentric weatherman whose Boke and Tsukkomi antics form the core appeal of their program. Koganei is a talented newscaster whose misstep in covering a conflict-of-interest story got him downgraded to the early bird slot at Chou-Hayaoki TV. Amasawa in contrast is a free-spirited weather "fairy" on the program who does all his reports in elaborate cosplay. Under Amasawa's influence, Koganei begins to become more comfortable with his place at Chou-Hayaoki and falls in love with Amasawa, but, despite his apparent outgoing personality, Amasawa persistently keeps everyone at a safe distance.
The first volume covers their work relationship and inevitable romantic one, while the second volume involves another newscaster attempting to break them up while Koganei is on a work exchange in America. Overall a light-hearted and sweet Boys' Love story with a charming cast.
The Weatherman Is My Lover provides examples of:
- A Storm Is Coming: Used both literally and dramatically. Amasawa is perfectly able to predict the typhoon that kills his parents but wasn't able to convince them not to go when he warns them about it.
- Bunny-Ears Lawyer: Although Amasawa's general behaviour and his odd cosplay habit are actively used to draw in viewers of the program, it is something he seems to do regardless and is also likely what keeps him confined to the early bird program.
- Closed Door Rapport: Koganei goes to Amasawa's apartment when he skips out from work and they have a heart-to-heart on opposite sides of the door, culminating with Koganei's request, "Won't you let me in? Let me into your heart, Amasawa." Amasawa decides to take his chance.
- Delayed Reaction: Koganei pauses unnaturally long twice after Amasawa makes sexual remarks on air. The first time he collects himself and continues as if nothing happened, making his response after the second time that much more satisfying as a proper Beat moment.
- Gay Aesop: Very, very briefly (and humorously) appears when one of the ADs asks how they're supposed to act around Koganei and Amasawa now that they know they're together, and the other give a brief True Companions speech"Koganei-san and Chitose-san are both our precious casters! We all love them!! So what if those two discovered that their feelings for each other ran a little deeper? You see some kinda problem with that!?"
- Home Porn Movie: Filmed by the ADs not quite intentionally (see below), which they then sealed off and labelled "forbidden."
- Hot Springs Episode: In the extras, the cast and crew of the program go to an onsen. The ADs get the job of secretly recording Koganei and Amasawa in hopes of fanservice shots for the audience. They end up with more than they bargained for.
- It's All My Fault: Amasawa's parents assumed his warnings about the weather were simply a cry for attention. Amasawa still blames himself for not being able to convince them otherwise.
- I Will Wait for You: A rather mundane version, but Amasawa actually supports Koganei going overseas to work and convinces him that he'll be okay without him and wait for him to come back.
- Loners Are Freaks: Amasawa considers himself this way. Koganei thinks they don't have to be alone.
- Love Redeems:"You're the one who changed me, Amasawa. And I'm sure you already know...that I'm the one who can help you change."
- Manic Pixie Dream Girl: Amasawa to Koganei, although he turns out to be more of a Stepford Smiler than he lets on.
- Manzai: Discussed as being the appeal of the program the characters star in, which would otherwise have very little audience thanks to its timeslot. Amasawa's silly antics are met with no reaction whatsoever by Straight Man Koganei and the audience is anticipating the moment he snaps.
- Nosebleed: Discussed and Played for Laughs. One of the ADs notes that the group trip is exactly the same as a school trip, except maybe the students who get nosebleeds from overexcitement. Immediately thereafter Koganei thinks through the implications of being at an onsen with Amasawa and has one.
- Paper-Thin Disguise: When Koganei and Amasawa don't show up for work one morning, the backup plan involves two crewmates and a pair of glasses, wigs, and a cosplay outfit. Fortunately for everyone involved they do show up in time.
- Stepford Smiler: Amasawa, whose guilt over his parents' deaths led him to avoid getting close to anyone while maintaining a bright facade.
- Straight Man: Koganei. Borders on Only Sane Man when the rest of the crew are deprived of sleep and coffee.
- Super-Deformed: While it comes as goes as needed for the most part, the producer of Chou-Hayaoki actually does not seem to exist outside of Super-Deformed mode.
- Triang Relations: Volume 2 features type 4, with Leon as a, Amasawa as b, and Koganei as c.
