Cosmo is 17 and the most popular boy in school. He is quite handsome and couldn't be helped but be liked/crushed on by almost everyone in school. His best friend, Poppy, is also the most popular girl. She's gorgeous and everything. Cosmo is the co-leader of the Red Cross youth club and cooking club and Poppy is the leader of the track team and cheer captain.

Cosmo started dating Poppy but he never loved her. She had an older brother (Sprout) and Cosmo only loved him.

While Poppy was out shopping at the mall, Cosmo and Sprout were alone at the house. They were in the bedroom, making love. Muffled moans and whimpering could be heard through the door if you listen closely.
