It absolutely has to be super sweet!! No angst!! No angst!! Lots of doting! Both leads must be completely devoted to each other! No misunderstandings, and no showbiz setting. Ideally under 500 chapters. My reading list is completely dried up.
The story is very original, not the clichéd story of a substitute marriage. It includes elements of farming and cooking. I only disliked the part in the latter half where the female lead slightly leaves the male lead. Otherwise, I give it full marks (it would have been even better if the female lead loved the male lead a little more).
