Answer:
The correct answer is sentimental.
Step-by-step explanation:
In the poem Love in the Moonlight you can see a lover addressing his beloved one.
Apparently he wants to meet his love at midnight and he asks if he is loved back.
The tone in a poem is the attitude that a person feels when reading it, and the attitude that the writer wants to convey to the readers.
In this case, the tone is merely sentimental.
