Premieres sometime in 2025. There is a teaser PV here as well as an announcement visual (bottom of this post). Synopsis of the source manga from AniList:
In today’s Japan, “rental” services can deliver an afternoon with a “friend,” a “parent,” even a fake girlfriend! After a staggering betrayal by his girlfriend, hapless freshman Kazuya gets just desperate enough to give it a try. But he quickly discovers how complicated it can be to “rent” an emotional connection, and his new “girlfriend,” who’s trying to keep her side hustle secret, will panic when she finds out her real life and Kazuya’s are intertwined in surprising ways! Family, school, and life all start to go wrong, too… It’s sweet but naïve boy meets cute but ruthless girl in this 21st-century manga rom-com!
Announcement visual:
Someone spoil it for me. I watched the first season and just cringed at how much money he spent on her. Not watching the other seasons but I’m curious if they actually get together. Whether in the anime or manga.
I stopped reading a couple months back, but I can relay what I know as the manga is still ongoing…
Manga Spoilers
tl;dr - They are not yet together from what I read
They end up living together for a while due to some construction kicking them out of their apartment building. Chizuru ends up getting confessed to by one of her actor friends but doesn’t end up accepting the confession.
Beyond where I read, just skimming through some chapters, it looks like Kazuya ended up asking her out on a “real” date (as opposed to a rental) and he is currently in a date planning arc. So, who knows how long it would actually be before the date actually takes place. 80% of each chapter consists of bystanders talking about how good Chizuru looks or Kazuya freaking out in his own head.
