## Early life and debut

Kim Kang-hoon was born in 2009 in South Korea.<sup>[3](https://asianwiki.com/Kim_Kang-Hoon_%282009%29)</sup> He first appeared on television in 2013 at age four, on the MBC Every 1 variety program *Today from Mom and Dad* (오늘부터 엄마아빠).<sup>[2](https://enews.imbc.com/News/RetrieveNewsInfo/444628)</sup> He moved into acting in childhood, with early film credits including *[Lucid Dream](https://www.edgepedia.org/lucid-dream-2017-film)* (2017), in which he played Choi Min-woo, and *Because I Love You* (2017).<sup>[3](https://asianwiki.com/Kim_Kang-Hoon_%282009%29)</sup>

His first widely noticed television role came in 2018, when, at age nine, he played the young Eugene Choi, the child version of Lee Byung-hun's leading character, in the tvN drama *Mr. Sunshine*.<sup>[4](https://agetrail.com/people/kim-kang-hoon/)</sup> The drama is among the credits Korean media list when describing how his name became known.<sup>[2](https://enews.imbc.com/News/RetrieveNewsInfo/444628)</sup>

## When the Camellia Blooms

**The breakthrough role.** In 2019 Kim played Kang Pil-gu, the eight-year-old son of single mother Oh Dong-baek (Gong Hyo-jin), in the KBS2 Wednesday-Thursday drama *When the Camellia Blooms*.<sup>[1](https://www.yna.co.kr/view/AKR20191129143400005)</sup> Pil-gu, who grows up early to protect his mother, became known to viewers by the nickname "Kkang Pil-gu" (깡필구).<sup>[8](https://www.tenasia.co.kr/article/2019112914314)</sup> The drama ended on November 21, 2019, with a peak viewership rating of 23.8 percent.<sup>[8](https://www.tenasia.co.kr/article/2019112914314)</sup>

Kim won the part at audition. Director Cha Young-hoon said he passed "overwhelmingly," explaining that Pil-gu needed to express a wide range of emotions and that Kim was the best fit for it; screenwriter Im Sang-choon, who judged the audition, also praised his reading.<sup>[1](https://www.yna.co.kr/view/AKR20191129143400005)</sup> Kim's mother, Yoo Si-jeong, said she had not expected him to pass, because the character was written as eight years old while Kim was a fourth-grader and tall for his age.<sup>[1](https://www.yna.co.kr/view/AKR20191129143400005)</sup>

The role earned him the nickname "the tear button of *Camellia*" (동백꽃의 눈물버튼) in Korean press, after scenes in which Pil-gu cries, such as when his mother changes the front-door password or reacts to her remarriage, became among the drama's most discussed moments.<sup>[1](https://www.yna.co.kr/view/AKR20191129143400005)</sup> In interviews during the run, Kim said that being told he acts well meant more to him than being called handsome or cute, because becoming a good actor is his goal.<sup>[9](https://v.daum.net/v/20191129060316476)</sup><sup> • </sup><sup>[8](https://www.tenasia.co.kr/article/2019112914314)</sup> He credited Gong Hyo-jin, who texted him as "son" and coached him on how to cry in scenes, for making the set comfortable.<sup>[8](https://www.tenasia.co.kr/article/2019112914314)</sup> Director Cha noted that his acting visibly improved across the series, singling out episode 18, in which Pil-gu returns to his mother after visiting his father, as an episode Kim "carried."<sup>[9](https://v.daum.net/v/20191129060316476)</sup>

For the role he received a youth acting award at the 2019 KBS Drama Awards.<sup>[4](https://agetrail.com/people/kim-kang-hoon/)</sup>
