How to say about love?

Roberto is an ordinary boy who plays with his friends and dreams of flying on a rocket to the stars. For him, the world embodies adventure. And then one day he sees Isabella, a little lover of butterflies, and his... heart is filled with a tender feeling that he had never known before. Roberto is in love, for the first time in his life!
But how could he tell Isabella what he so wanted to tell her? After all, these must be some special words. And you need to convey them to the girl in a special way. Maybe shout about your sympathy from the highest tower? Or write on pieces of paper how much he likes Isabella and hang them all over the city? Or maybe rise into the sky and...
Roberto has many ideas, but in the end he understands that his statement about love must be sincere and intended only for Isabella. He thinks about what Isabella really is like, what interests her, what is close to her, and gets to work.
