TVN drama 'Why is Kim Secretary?' Park Min-young doubted his brother's Identity as a child.
In the ninth episode of "Why Will Secretary Kim Do That," Kim Mi-so asked Lee Yeongjun (Park Seo-joon) "Is his brother really Lee Sung-yeon (Lee Tae-hwan) writer when he was a child" and Lee Yeongjun replied, "Yes." However, Kim Mi-so did not doubt that his brother was like a vice chairman, referring to Lee Yeongjun's trauma.
Lee Yeongjun has confirmed Kim Mi-so's heart and Kim Mi-so also expressed his affection for Lee Yeongjun again.
The Identity of his brother as a child with a secret raises questions.
