Well, this makes me think a bit more. You said 'wrong impression' but how does that make a wrong impression? I think 'beautiful' combines everything and expresses the interest in a somewhat romantic way. It is always your choice to show it back or not. I don't think it is wrong to have romantic interests, it is natural. You also might have your own, and to show it to the person of your interest you would also use some words, maybe 'handsome' etc. And that is completely okay I think, not wrong. Emotional intelligence attracts people socially and if you get a lot of 'beautiful' word then you must be socially very good. Thats all, I would say.
Anyway, putting our views aside, you did a great job with the poem, expressed yourself well and words rhymes well.
