Is this grammatically correct? What does it mean? Am I the only one this song makes to tear up?

The sentence "Am I the only one this song makes to tear up?" is almost correct but would sound more natural if it were phrased slightly differently. A better way to say it would be: "Am I the only one this song makes tear up?" The meaning of the sentence is that the speaker is asking if they are the only person who feels emotional or starts to cry when listening to the song. The phrase "to tear up" means to become emotional to the point of having tears in one's eyes.
