Jungwoo expressed great affection for Mark.
On October 16, NCT 127 guested on JTBC's 'Idol Room'. During the 'Fact Check' time, the members and the MCs talked about Mark's charm points.
Jungwoo said, "I liked him from the very beginning. The way his dimples form when he smiles is so charming." He then startled Mark by confessing, "I just like him." Fellow members went wild at Jungwoo's confession, but Jungwoo remained very calm.
Ultimately, Jungwoo beat Doyoung and Jaehyun, and managed to become Mark's "other half".
