An encounter in the spring, the budding of spring. What do you think of an agricultural otaku? The comedy between beauty VS agricultural otaku will now start!
I like how Silver Spoon and Toretate Crazy are mangas about agricultural practices. It's a shame though that Toretate Crazy is only a oneshot. I actually liked how the guy MC gushes over farming. He reminds me of Bakarina from Death Flag Otome since they're both agricultural freaks (meant it in a good way btw). While Toretate Crazy is mainly focused on the possible love story between a beauty (who had insecurity complex after she overheard the person she likes call her boring), Silver Spoon delivers a more well rounded approach. Both are definitely worth the time to read.
