Benjamin Herrmann is a cynical loner, cold and close-minded. However, that won't help him as his mother secretly signs him up for a student exchange program. Now he must spend a year in Japan, at the Tatsuya High School finishing a checklist that needs him to be the exact opposite of himself.
On arrival he meets his assisting student: Mizuho Sakiyurai. She makes it their mission to finish the list by the end of the year and tries to break down the walls around her new friend from the west.
Benjamin is promptly called to the principal's office for an important information, it would seem that he got signed up for a student exchange program! Poor Benjamin must now deal with that information by mumbling how dreadful his life is. Ms. Schulz still believes that Benjamin can change his view on life...But he will need some help in doing so...
