Probably not what you're talking to because this one's old as fuck, but Oh My Goddess! pulled a similar shtick back in the day and caused a meltdown of hitherto-unseen proportions on /a/. Think this might have been... 15-ish years back?
>entire series revolves around an average college student who puts in a wrong phone number and happens to call some sketchy "Goddess Helpline"
>call is answered by a literal angel, guy gets one wish
>naturally, wishes for the angel to stay with him forever; they become a couple and quickly get very lovey, but this being a late 90s/early 2000s story, the MC is a spineless cuckold 99% of the time
>takes years to hug, years to kiss, seggs is still just a distant dream
>romance progresses at a glacial pace, but after literally 16 years of releases, the story finally reaches its climax
>author decides to make it so that the angel, being a divine being, actually dampens impure thoughts like sexual urges just by merely existing near the MC
>in other words, due to this last-minute lore introduction, MC was effectively magically castrated for the entire series
there's something in the water in japan and korea that makes them pull this shit, i swear to god
