A humorous novel about the quirks of men and women. Sunny boy Basti has always had everything handed to him. But then he suddenly loses his job, his girlfriend Kathy wants nothing to do with him anymore, and he finds himself nearly broke and homeless. As a last resort, he sneaks into a lively girls' shared apartment by pretending to be gay. As the only guy in the house, Basti experiences the mysterious world of women. His roommates share their flirting strategies, styling tips, and diet plans with him. So this is how women tick? Everything would be fine if Basti didn't fall head over heels in love. But who has captured his heart: the gentle Marie, who prefers to spend her time passionately studying birds? The sexy chaos-bringer Felicia, who always ends up with the wrong guy? Or the clever and worldly Bea, who seems to have no one interested in her? It all becomes increasingly complicated for him.
