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 ☆☆

For example,
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!)
