First ones that came to my mind.
https://www.mangago.zone/read-manga/seifuku_no_jo_ou_sama/ - manga, it's more SM theme, but it's with young characters, really mild and without smut. There is quite a lot od second hand embarassment tho XD
- https://www.mangago.zone/read-manga/the_sensual_m/ - manhwa with adults trying BDSM, also mild and without smut
Maybe try to read before you show it to her, because I don't want to be cause of her trauma XD
Kabukicho Bad Trip is a rlly good one! You have to check the freak levels on that one though, I think it was on the mild side but I don't remember well loll
A really cute one that came to mind is obnoxious hero-kun. I think it should be suitable even for people who dont like bdsm
This is kind of a strange request but my sister is curious about BDSM when I was describing one of the manhwa that I have read. So she wants a recommendation herself an I'm at a loss. Can you suggest a BDSM manhwa (manga is also okay) that won't freak her out lol. Thanks!
