Do you know the meaning of 普通に（hutsu-ni）？
普通 means “normal”
普通は means “normally” “usually”
but 「普通に」means a bit different.
Japanese usually use it when they want to praise something in a casual way ☆☆
これ普通においしい！ （this is pretty delicious!）
Don’t be confused when Japanese use this phrase, and try to use it!
(You would look very Japaneseyyyy!)
