Poem interpretation?

Hello folks!

Tomorrow I'm writing a class test on poetry interpretation. I've been searching for a suitable poem to practice for a good half hour, but unfortunately, none are particularly good.
Since we've covered the poem "He doesn't know if he loves her" in the last few lessons and even listened to a podcast about Erich Kästner, I suspect we'll have to interpret another one of his poems. Unfortunately, I can't find one online.
That's why I'm asking for a few poem suggestions. They don't have to be by Erich Kästner, but preferably from the Romantic era or with a theme about love.

I look forward to nice feedback😊
