Cosmo and Sprout are best friends despite Cosmo's personality and things. Cosmo was 5 years old and Sprout was just 4 years old up until Sprout went missing awhile back.

12 years later and 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 (new) 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.

Despite everything, Cosmo still misses Sprout. Little did he know, Sprout was found and able to return home a few weeks ago. He was enrolling in the same high school Cosmos at (without Cosmo’s acknowledgment). He had Vee help him at times around the school.
