They are half-brothers, so it is incest. So, warning to anyone who is not comfortable reading this. For those who do want to read, the webtoon is not explicit. There is not even a kissing scene if I remember. But I do remember seeing hickeys at one point - other than that, nothing sexually explicit.
I just remember there is a bit of touching on the stomach area (I think that would be called molesting, right?) in the beginning - but other than that, nothing sexually explicit.
actually it wasnt shown in the manhwa but in the novel yongshan r*ped yongqi
I havent read this yet but are they brothers like incest brothers or just bros being bros?
