One thing I find quite interesting is that this manga and two other manga are part of the same universe and actually occur at the same time. The two other manga I'm talking about are:
"I'm the Older Brother of a Famous VTuber, But for Some Reason I Became Famous"
"The Teen Web Novelist is a Girl Magnet: Now My Crush Feels Bad for Rejecting Me!"
One thing in common is that the main characters of all of these manga all contribute to the downfall/bankruptcy of the Tanagawa? Company (I don't remember the exact company but let's call it that.)
For example, the main character of the teen web novel manga is the author of the number 1 light novel in the country, affiliated with Tanagawa Publishing. His father is also an editor for the same company, and after seeing how corrupt and black/bad management company Tanagawa is, he decided to create his own publishing company. This chad of a father decided to persuade his son and his editor to join his new publishing company, alongside with other notable authors to jump ship with him. This also includes the main character of the twins manga since he's also an editor in the same company as well as the author he's overseeing. So Chad Father managed to create a new company and pretty much gather the top talents of the previous company, leaving the previous company devoid of their top IPs.
And to top it all off, the main character of the Vtuber manga was in a relationship with the daughter of Tanagawa company, but since the daughter was a POS and mocked the MC, this left him heart broken, which was leaked into the Internet from his sister's unmuted Vtuber streamer moment. This basically caused a scandal with Tanagawa Company, becoming the fuse that reveals all their corruption and misdeeds, ultimately contributing to their downfall.
The editor MC of the twins manga is supervising/editing a young adult author, who is secretly the granddaughter of the top conglomerate of Japan, let's call them Kaga Conglomerate. After Tanagawa dismissed the MC editor, they sent a new editor to the author, who treated her like crap and made her cry. After switching to the MC editor new company, the grandfather and CEO of Kaga Conglomerate decided to screw over Tanagawa Company and drive them to the ground for messing with his granddaughter. He's also the one who pulled the strings to allow harem marriages to Japan, which will benefit all three MCs from all three mangas since they all have their respective harems (he only really did it for the editor MC since his granddaughter loves him and he approves of him).
Hell, we even have crossover characters between the mangas/novels. The MC editor knows the editor of the Light Novel MC, who's a woman and also in the LN MC harem. The security guard family (Kaido I think) of the Kaga Conglomerate appears in all three mangas. I believe the mother of the guard family runs the Vtuber company (of Kaga Conglomerate) of the Vtuber MC, and the eldest daughter is part of the MC editor harem and former college buddy, and one of the guard brothers also appears in the Vtuber manga to fetch the MC to the Vtuber company. My GOAT security brother character appears in all three mangas/novels I think. Characters from other manga/novels are even explicitly mentioned.
There's more details in the manga and especially the novels, but damn, it's quite amusing to see the downfall of the Tanagawa Company from various angles. And also this apparent shared universe between these characters and manga/novels.
