There's this pornhwa that i read back then titled 잘하는 매니저 (english title: Good Manager. Although it hasn't been scanlated yet. I read it at toonkor.red) Spoiler: If you're curious about the story basically it's about a manager banging his(what? His idol? His client?) anyway he's banging them with a bit of mind control(temporarily, just before and during sex, so he doesn't have full control of them.) oh yeah, he fucks the idols one at a time. So no 3some or 4some. And obviously no NTR element. Though there's a bit of a hint here and there but nothing serious. His mind control though, happens when he takes off his glasses.. Yeah, our MC here is wearing glasses. It's nice too read and *ahem* as a nice research materials too. My favorite girl is Kodi. Soooooo Here I am looking for another of the same genre.. No ntr, no swinging, and you know... Just the typical heartwarming(?) stuff.. Edit: quick question- does pornhwa have incest?
My current favourite is perfect half, no ntr till latest translated chapter. But i am pretty sure it will be a harem
haaaa . . . there was a title or two that i tried reading some time ago . . . if i remember correctly the title, it was SStudy?? and demn. . . . maybe it really is not my type of tea. . . .
She is Young / Little Girl i haven't read it. but i think there is no NTR Spoiler: heroine both girl are the same, only different timeline
My Sister Has Amnesia - What's Sex? for the non-ntr Hahri's Lumpy Boardhouse also you can search in my collected pornhwas(though it was mixed with ntr)
