Girls' Generation's YoonA and young actor Lee Chae Min are at the center of controversy after their on-screen kiss in 'Bon Appétit, Your Majesty' set social media abuzz with a combination of excitement and outrage.

The hit K-Drama has been met with criticism over the 10-year age difference between its stars, with some wondering if the casting was accurate.

One netizen said, "I honestly cannot see the age gap while watching the series. So, people are nitpicking, as usual, and surprise, toward a female actress...."

In spite of all the debates, a lot of fans have commended the series for being charming and for the undeniable chemistry between the two stars.

A fan said, "Honestly, I am always seeing complaints when it's older woman and younger man, If it's the other way around the complaints are almost none existent.

I don't get it. Because both are adults. Playing adults, plus Yoona is really pretty, and the chemistry is nice."

In the latest episode, fans were caught off guard with a romantic kiss scene. The scene starts with Lee Chae Min looking at YoonA's eyes and then leaning in to kiss her.

As described by fans, "Before he gently kisses her, and while YoonA seems shocked at first, it deepens, and the two seem immersed in each other."

The scene becomes more intimate as the actors hug. One of the fans commented, "NAHHH this chemistry is insane.

The way Lee Chaemin looks at Yoona??? Like, HELLO?? So much unfolding in his eyes. THEY KISSED, and my soul left my body fr. So gentle and wholesome."

The scene was soon shared all over social media, with many of them pointing out that it is unusual for a K-Drama to have that much intensity so early on in a show.

One fan penned, "OMG WE GOT THEIR FIRST KISS SCENE ON EP.4 !?."

The romance plot has helped make Bon Appétit, Your Majesty one of the rising fan favorites, as viewers are drawn in both by the conflict and by the blossoming romance between the protagonists.

Though the issue of age difference continues to sit at the forefront of controversy, a majority of online reactions have been focused on the undeniable chemistry between YoonA and Lee Chae Min.

As one viewer summed up, "I didn't expect this type of kiss scene so early on, but now I am eagerly awaiting the next episode."
