this whole pfw wonbin drama happened because fans wanted to lie about his flight in october which does exist but is to tokyo for his solo fansign. it was never for fashion week to begin with & like the last person said sept 30th was always their end of vacation. str solo flight back to seoul from japan on the 30th had been booked since end of july/early august. the plan was always for a long vacation they even filmed their mv a week before they left for their last schedule in september (in japan)
