Despite Jin Seok being married and having a son, he still continued his special friendship with Chan Young; unfortunately, his wife is sensing something about the two; hence, the confrontational scene.
On the other hand, the new still cuts also featured how Cha Mi Jo is protective of her best friend.
Seeing that Jung Chan Young couldn't defend herself, she stepped up and confronted Kang Seon Joo.
Surprisingly, Mo Ji was the most unsupportive of Jung Chan Young and Kim Jin Seok's odd relationship, which raises the curiosity as to why she's brewing with anger.
It is safe to say that since Mi Jo knew about Chan Young's health crisis, she has become more protective of her.
In the last episode, the dermatologist was surprised to find out that her best friend has stage four cancer and doesn't have the courage to tell her.
Still, in a state of shock, she went straight to Kim Jin Seok's office instead and blamed it all on him. This is also the first time that Kim Seon Woo (Yeon Woo Jin), who was at Jin Seok's office, saw the vulnerable side of Mi Jo.
"Thirty-Nine" episode 3 is scheduled to broadcast on February 23 at 10:30 p.m. KST and can be streamed via JTBC and Netflix.
