Seventeen has kicked off their first world tour with their concert at the Jamsil Auxiliary Stadium in Seoul.

The boys saw 30,000 fans over the course of 3 days from July 14 to July 16. On each night, they performed for about 3 hours, starting with "Pretty U". The first half of the concert was the 'water' concept, and then the boys moved on to the 'fire' concept.
