there was this couple that had an arranged marriage and the uke got pregnant. I think it had something to do about family traditions. I am not quite sure but I think it had something to do about a flower (that helped the uke to get pregnant?) I don't remember the title of that manga and I wanted to read it again, seemed like I forgot to bookmark it. It was sort of supernatural type of genre. Please if anyone knows let me know please or reply to this post. Thank you very much in advance! (▰˘◡˘▰)
