Premieres January 12, 2025. Check out the ANN article for additional information. Synopsis for the first season from AniList:
Rentarou Aijou was rejected 100 times in middle school. He visits a shrine and prays for better luck in high school. The God of Love appears and promises that he’ll soon meet 100 people he’s destined to date. But there’s a catch—once destiny introduces someone to him, the two must happily love each other. If they don’t, they’ll die. What will befall Rentarou and his 100 girlfriends in high school?
And the subreddit is completely okay with this. They’re like “oh he HAS to date his cousin because she will die…” “It’s fiction” “it’s a harem anime, incest was expected” etc
Without ever stopping to think…you know the mangaka could have just said “no I’m not writing that?”
Are you new to manga and anime?

I think no one really pays attention to fictional age in anime. People tend to enjoy the show.
