All chapters in volume 1 with Maya and Nemugasa is straight up sexual harassment. It's acknowledged early on by other people, and also way later into the story, this time with with the instigator.
Drama CD available.
"You're gay to the core. Why do you keep falling for normal guys...?" - Soohan Woo
It's got a slew of Korean drama tropes (rich people, revenge plot, kidnapping, accidents, tragic character(s)), but you'll find yourself not minding due to the well-written ensemble cast.
Chapter 62 has implied rape (fade-to-black sort of thing), but it was neither acknowledged nor resolved.
A love story that's focused on the insecurity of a gay man going (Tozaki) out with a straight man (Kurata), compounded by the fact that said straight man has trust issues brought about by family drama.
The rape in chapter 4 isn't treated as a romantic catalyst, but is an integral part of the story.
Drama CD available. Adapted to live-action.
Dubious consent abounds this lovely story between a pre-school teacher (Nozomi) and a yakuza head's son (Tatsuyuki). Tatsuyuki shines as this incredibly kind and emphatic character when he goes through similar incidents of blackmail, first with Nozomi, then with Rogi.
Chapter:
1 - Rape (Nozomi acknowledges and apologizes in a later chapter)
4 - Child abuse (flashback)
6 & 7 - Sexual Harassment (Rogi)
Drama CD available.
This is a story of ex-lovers who takes a second chance when they meet again in university. There's depiction of non-romanticized rape when the couple fought. No acknowledgement yet as of latest available chapter.
Drama CD available.
Yandere/Tsundere couple.
Not sure if it would make sense to read it, but I'd go directly to Chapter 0 (Chapter 9) which is when they meet if you want to skip the rape and frankly, Stockholm Syndrome arc of the first 8 chapters. Anything after those chapters are a gem of a story, and I'm saddened by the fact that it had to start that way.
Drama CD available, anime adaptation deviates to remove the rape content.
"Hey, Shibuya, what color are your panties today?"
"Hey, Honda-san, do you want me to beat you up?"
Shibuya loves wearing men's lingerie, and unfortunately, Honda likes seeing Shibuya wearing them and he doesn't care about his methods to accomplish that task (many, many times).
Chapter:
Sexual harassment every chapter Honda forces Shibuya to show his lingerie.
2 - Rape
"I'm supposed to be an ex-convict. Doesn't that bother you?" - Sugimura
Much like their personalities, their romance is quiet and straightforward. They have concerns and act out what befit their age honestly. It's probably why they click despite the major age gap.
Chapter:
1 - Sexual Assault (bullies)
2 - Attempted Rape (bullies); dubious consent (Sugimura)
There's so much dirty, bad, wrong in this series, but when the author does fluff and romance, she does it so good. Start with the second couple on chapter 19 to avoid the worst of it.
Chapter:
1 - Public indecency
4 - Groping
5 & 6 - Rape
7 & 8 - Coercion
9 & 10 - Rape
Behind Story 1 - Rape
23 - Sex with a minor (flashback)
25 - Non-consensual BDSM
47 - Rape
It's only through how interesting these two characters are that they remain on this list. Yamashita elevates this manga to a memorable read with his earnest yearning for love. Asaoka, Mr douchecanoe and epitome of the bad guy archetype, is portrayed as someone with low EQ, but does develop as a character.
Chapter:
1 - Rape
2 & 3 - Sexual Coercion
Drama CD available and highly recommended. Shimono Hiro (Yamashita's seiyuu) was brilliant in this.
