The plot is similar in my opinion. While our MC in One Million Yen Girl moves around, the MC in Little Forest simply moves to a rural area (and Little Forest is focused on cooking while One Million Yen Girl isn't). But, I feel like both MC's are running away from themselves until eventually they come to face themselves. The vibes are pretty similar too: pleasant melancholy all around. Similar aesthetic and cinematography in my opinion too.
I recommend this both drama because , Male lead and Female lead
