Are you sure about "Like!"?

a message from a private university

There was an advertisement like this in the car of a subway in Kyoto. “Reality may be more complicated.” reads below. If a story moved you deeply, you should express your feelings in words. If you felt something strange about it, you should say, "Don't you think you can say like this?" It is your pride. If the story struck your heart, you should develop the story,  not close it with "Like!." A university is a place where you can learn auxiliary lines to do it.
