Premieres July 3, 2024. The new PV is here. Check out the ANN article for additional information. Synopsis of the first season from AniList:
When a pregnant young starlet appears in Gorou Amemiya’s countryside medical clinic, the doctor takes it upon himself to safely (and secretly) deliver Ai Hoshino’s child so she can make a scandal-free return to the stage. But no good deed goes unpunished, and on the eve of her delivery, he finds himself slain at the hands of Ai’s deluded stalker — and subsequently reborn as Ai’s child, Aquamarine Hoshino! The glitz and glamor of showbiz hide the dark underbelly of the entertainment industry, threatening to dull the shine of his favorite star. Can he help his new mother rise to the top of the charts? And what will he do when unthinkable disaster strikes?
I personally think there was an extremely vocal portion of the fanbase that made that a way bigger deal than it actually was.
General Discussion of Aqua's Relationships
I think what you are talking about is the Aqua X Ruby incest supporters. It was a thing for a couple chapters after they both figured out who they were in their past lives. In the latest chapters, Aqua has come to terms with the fact that he actually has feelings for somebody else. He is not the doctor that he was in his past life, and he doesn’t feel that way about Ruby after living with her as brother and sister up to this point. We don’t yet have a lot of insight into Ruby’s thought process, so it is quite possible that she is still crushing over Aqua because she loved her doctor in her past life.
I think the main thing that drove this portion of the fanbase into overdrive was that Aqua and Ruby have a kiss scene in the movie they are shooting together. However, they are both professionals at the end of the day.
