Lee Yi Kyung, Sohee, Shin Hyun Soo, & Kim Sun Ho being considered as leads of 'Welcome to Waikiki' season 2

Due to the widespread success of 'Welcome to Waikiki' season 1 which aired February through April of this year, the drama will be returning with newer content in season 2, some time in early 2019. According to reports on November 14, it seems that former Wonder Girls member and actress Sohee has been offered a female lead role in season 2 of 'Waikiki'. It's likely that season 1's female lead Jung In Sun and male lead Kim Jung Hyun will not return for season 2. 

However, another season 1 male lead, Lee Yi Kyung, is currently considering appearing again on season 2, according to media outlet reports. Alongside Lee Yi Kyung, rising actors Shin Hyun Soo (currently appearing in '12 Nights') and Kim Sun Ho (recently appeared in '100 Days My Prince') have been offered male lead roles, with Kim Sun Ho's side "in the final stages of adjusting schedules". 

Director Lee Chang Bin of season 1 will be returning again for season 2 of 'Welcome to Waikiki'. What do you think of the potential casting above?
