1. An aerosol generating system comprising:
an aerosol generating device comprising a first vaporizer configured to generate a first aerosol by heating a first liquid composition, a second vaporizer configured to generate a second aerosol by heating a second liquid composition, and a controller configured to control the first vaporizer and the second vaporizer; and
an aerosol generating article accommodated in the aerosol generating device and indirectly heated by heat generated by the first vaporizer and the second vaporizer,
wherein the controller is configured to control power supplied to the first vaporizer and the second vaporizer, based on a first mode, in which a smokeless aerosol is generated, and a second mode, in which a transport amount of nicotine included in the aerosol generating article is adjusted,
wherein the first vaporizer comprises a first hollow portion,
wherein the second vaporizer comprises a second hollow portion,
wherein the first vaporizer and the second vaporizer are detachably coupled to each other, and
wherein, in a state in which the first vaporizer and the second vaporizer are coupled, the first hollow portion and the second hollow portion form a hollow into which the aerosol generating article is inserted.
