Of Course I Will Marry My Good Brother After Becoming a Succubus

[Change marriage + boy-girl + succubus + science fiction + fantasy] It's different from the traditional change marriage~ Because the female protagonist originally likes the male protagonist (if you don't like it, don't criticize her), the plot will be quite different from traditional transformation stories. The little succubus is pure love~ But there is no guarantee that you will be forced to have sex ~ (The plot requires it, don't comment if you don't like it) The author is slow (lazy) in writing, and it is useless to remind him. The fastest update is daily. If the writing is stuck, monthly update is not impossible.
