Among the list of ongoing K-dramas, Our Universe has quickly become a fan favourite.

Directed by Lee Hyun-seok and Jung Yeo-jin, the rom-com features actors, Bae In-hyuk, Roh Jeong-eui, and Park Seo-ham in leading roles. However, apart from the adult leads, the youngest star of Our Universe, Park Yoo-ho, has quickly captured everyone's hearts.
Many viewers of the series, taking to their social media, jokingly asked if the child was real or AI, given how perfect he appears and his expressiveness on screen. It is worth mentioning that Park is only three years old. This is why his impeccable timing, reactions, and the natural comfort he brings to his acting make him truly seem unreal. At such a young age, Park Yoo-ho effortlessly steals scenes where even experienced actors often face trouble. If you are interested in learning more about Park Yoo-ho, the toddler who has sparked endless memes, praise and other discussions on social media, keep on reading.
Park Yoo-ho was born in South Korea to his parents on August 25, 2023. This, as we have already previously mentioned, makes him only three years at the time the series, Our Universe is airing. Now, although he is truly young, this does not mean that he has no social media presence. For those unaware, his Instagram account has nearly 638k followers. It is worth noting that the account is run by his mother, as is clearly mentioned in his account's bio. It is his adorable snaps which quickly helped him amass such a huge fan base on social media, in addition to his acting on Our Universe with some of the most popular actors.
More often than not, netizens express how much they admire Park Yoo-ho's natural charm. Apart from praising his genuine acting skills, a number of social media users call him “too cute for words,” and they are not wrong. While the lead cast of Our Universe, Bae In-hyuk, Roh Jeong-eui, and Park Seo-ham, are well-known in the field and have a huge fan following, many viewers of the rom-com series claim that they watch the show only because of Park Yoo-ho's adorable yet phenomenal acting.
In the hit ongoing K-drama series, Our Universe, the 3-year-old Park Yoo-ho plays the role of a toddler named 'Seon Woo-ju'. Well, in the series, he is actually 20 months old, and after the sudden death of his parents, he is brought under the guardianship of 'Seon Tae-hyung,' played by Bae In-hyuk and 'Park Yoon-seong,' played by Park Seo-ham. If you are wondering about the connection between Park Yoo-ho's 'Woo-ju' and the two, his father was the brother of 'Tae-hung', and his mother was the sister of 'Seo-ham'.
As you can already guess, ‘Woo-ju’ is not just a simple prop but rather an integral part of the story. It is through Yoo-ho's character that the adult leads navigate their sudden parenting roles, which is fundamental to transforming their relationship. Episode after episode, his character's sweet, innocent, and playful nature keeps viewers hooked, as it adds humour and heart to even quiet and reflective moments.
While Park Yoo-ho's on-screen moments have left the viewers of Our Universe obsessed, the same is also true for his behind-the-scenes moments. Well, many of the cast members and crew have openly talked about the positive influence Park Yoo-ho had on the set while they were shooting. During an interview, actor, Jeong recalled one of the sweetest and most memorable encounter which he had with Yoo-ho. She said that when they met for the very first time, 'Woo-ju' was genuinely scared of her because of her height. Despite this, one day he suddenly hugged Jeong after overcoming his fear. In her words:
“When I first met Woo-ju, he was a bit scared of me because I am tall. Then one day, he hugged me. It felt like I had the world, and that happy memory remains unforgettable.”
By now, there is no doubt left in our minds that Yoo-ho brings a kind of natural energy to the screen. Well, the reason behind this is that his energy led to a handful of unscripted moments, which were so beautiful and heartfelt that the makers decided to leave them in the final cut. This, as you can guess, lent the drama's realism.
It is clear to see that Park Yoo-ho is an adorable and cute child. However, his “cuteness” isn't the only thing that has made him popular with the series' fans. Viewers of Our Universe appreciate how his performance not only adds but also drives the emotional core of the romantic comedy series. His presence helps the adult leads come to terms with their fears, embrace the responsibility that has fallen upon them, and develop stronger bonds.
While there are only a few episodes left for Our Universe to end, this has not stopped fans from filling social media with clips and memes of Park Yoo-ho, with some even reacting specifically to his scenes. All in all, his reception among K-netizens and cinephiles ensures that Park Yoo-ho is a rising star to watch in the K-entertainment world.
