a bitch that likes to read's Questions (2)

i read this b4 but i forgot the title and i cant find it :(( its about a realistic sex life between a couple. i think its based on the author's own life with her husband. The husband works at office and the wife is a writer. The art style is very very cute more like a chibi version of them. That's all i can remember. If anyone knows this manhwa please tell me ヾ(❀╹◡╹)ﾉ~
