CORTIS has a four-million seller. According to Circle Chart, the group’s second EP, ‘GREENGREEN’, had sold about 4.1 million copies as of September 17.

That puts it in rare company. Only one other album released this year has crossed the 4 million line: BTS’ ‘ARIRANG’.

A big step up

The new total is close to double what CORTIS’ debut EP, ‘COLOR OUTSIDE THE LINES’, has sold so far. That’s a steep climb from one release to the next for a group this early in its career.
