In Love for the First Time: The Most Beautiful of All Illnesses. Karl has no idea what's happening to him. But every time Charlotte is near, he feels so strange, and whenever Charlotte looks at him, the most embarrassing things happen. Yet, Karl thinks Charlotte is pretty amazing. So he has to take action: Karl will write to Charlotte, invite her to the movies, take her out for ice cream... It's just unfortunate that Charlotte is leaving for vacation tomorrow morning - for six weeks! An eternity! But sometimes sacrifices must be made for happiness: skipping school, bending the truth a little, and fighting through the urban jungle. Determined, Karl takes on all challenges, because at the end of the rocky path stands Charlotte.
