After quitting baseball in his second year of high school, he accidentally transmigrated a character in a Japanese romantic comedy manga he had been reading. The character he possessed was a delinquent from the high school baseball team who had been harassing and hitting on the heroine. However, this guy was an absolute genius when it came to his talent as a pitcher. Whether it's Korea or Japan, or even a world inside a manga, it doesn't matter as long as he can play baseball here.
