Co-stars Suzy and Park Bo Gum of the sci-fi romance film 'Wonderland' displayed their real-life couple chemistry on the May 31 broadcast of KBS2's 'The Seasons - Zico's Artist'. 

On this day, the two stars opened their stage with a duet performance of "Somethin' Stupid". Afterward, host Zico introduced the 'Wonderland' stars, who expressed their excitement at being back in the KBS studio.

Suzy and Park Bo Gum also talked about their trending "couple photos", shot for the filming of 'Wonderland'. Suzy explained, "In the film, Park Bo Gum plays the role of my boyfriend. We needed a lot of 'old photos' together, but since we could not just take them all at once and change clothes after every shot, we decided to just snap the photos whenever we met up." Park Bo Gum added on, "If the film does well at the box office, more photos will be released." 

Additionally, Park Bo Gum opened up about participating as a composer and lyricist for one of the songs from the 'Wonderland' soundtrack album, titled "Wish". Suzy shared her thoughts after listening to the song, saying, "It felt strange, because it captured Tae Joo and Jung In's story so perfectly." 

Later on, the two stars also performed Suzy's "Satellite" and "Holiday" with Park Bo Gum on the piano, "Dream", and more.
