Lowkey adds to the plot and highkey a fetish shit. Also occurs between the mc and ml, twice. Plot is really good though I won't lie to you.
In the main story, no. IIRC, there is an "alternate universe" sort of 2-chapter story where the rape is between the main pairing; it's not canon, should you wish to skip it. Other than that, only the main character is subject to most of the rape you see tagged.
Are we forgetting that the first time between the main characters was also rape or...
I've seen there's a rape tag in this, is it between ml and mc? Does it add to the plot or is it just fetishisin?? I wanna know so I know whether to read or not
