Maybe people expect the rape as romance trope when there's a guy involved, but not when the characters are women.
Asian media seems to have a special place for rape in their heart. The shoujo het romances of the 90's and early 00's have so many heroes raping the heroines in the name of ''love''. Yaoi has always been rape-y. There is some rape in Yuri, but those are rare.
Even now, in Thai dramas rape is shown as a form of love. The twisted part is, somehow, the girl falls in love with the guy after all that. That's just unsettling and horrible usage of the rape trope.
