On one hand, I agree that the 'Rape is Love' trope is maximum cringe. On the other hand, it's true that IRL the majority of rape is commited not by strangers, but by those close to the victim, and yes, this includes romantic partners. And sometimes people do stay in abusive relationships for mindboggling (at least to the 'outsiders') amounts of time. Because its mainly a particular sort of people gets into them in the first place. But I don't want to bore you with my psychology tl'dr. I guess, what I'm trying to say here, is that in theory rape and romance can be mixed, but the majority of yaoi just fails at it. I don't read that much manga currently to be honest, but I wonder if there are any realistic abusive relationship ones out there. Which are not 'Killing Stalking', because that shit is just ridiculous, over the top and lame.
By the way, thanks for these comics! I've only seen the first one before, but it was ages and several hdd crashes ago. Was just thinking about trying to find it again the other day.
