Just when Choi Jeong Yo found a sliver of peace, tvN’s new music drama Four Hands, Two Sonatas yanks it away. Fresh stills from Episode 4 show Lee Jun Young’s character walking straight back into the danger he spent the last three episodes running from — and this time, it’s personal.
What’s Happening In The Story
Choi Jeong Yo had finally tasted joy: a fresh start at a new school, a reunion with old friend Kang Pio (Song Kang), and a triumphant four-hands piano debut. But loan sharks chasing his father’s debt caught up with him fast, and Kang Pio had to help him escape.
Now, instead of hiding, Choi Jeong Yo does the unthinkable — he walks into the loan shark’s office on his own. What he finds there stops him cold: his father, battered and broken. Moments later, he’s on his knees in front of loan shark Kim (Kim Min), begging for mercy, while Kim’s icy stare promises nothing good.
