I'd say give OZ a call, as that's really the only way to select specific seats in advance. It can't hurt to see if they will let you select those seats, although, the 744/74M seats in row 1 and 2 usually remain blocked until a few days to departure.

Unfortunately HKG-ICN has gone to A330 since
Next spring the latest OZ flight is back to a 744 or 74E.
