In Japan, there is a proverb that says, "If you chase after two hares, you will catch neither."
Koichi is always following the latest trends.
I will follow my dreams, no matter how hard it gets.
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means follow so the verb version is to follow (it's also to chase, because when you follow something you are chasing it too).
You've learned this reading already, so you should know how to read this word!
