One morning she appeared in the elevator. We silently ascended one hundred and fifteen floors. Then she entered the school with me. During recess, she stayed in the classroom while I stood at the glass balustrade of the terrace, repeating to myself over and over again, "Don't fall, don't fall, don't fall." I was afraid of falling in love. During lunch, she left and never returned to the college. It became imperative for me to find her again. This loving quest intertwines with an ecological struggle. The story offers a reflection on the environment and our planet, beautifully framed by the poetry of Timothée de Fombelle.
