So a Ronin is slang for a student that follows no teacher?
Its original meaning is "a samurai without a master", but in modern lingo, it's a student who doesn't immediately advance to higher education upon graduation, either to take time off for travel/self reflection/etc., which the "gap student" definition leans more towards, or because they couldn't get into any of the schools they applied to, such is the case with this and Slow Start.
