Many stars ooze with sex appeal and brooding charisma but did you know that some of them turn easily red as a tomato after one or two drinks? Though they appear very manly on the screen, some of them are adorably weak when it comes to alcohol.

Here are four popular leading men with low alcohol tolerance. Keep on reading to know more!

Kang Tae Oh

With his skyrocketing popularity, many fans were drawn to him even after the broadcast of his hit series "Extraordinary Attorney Woo" with Park Eun Bin.

Did you know that he can't drink much alcohol? In a brief appearance in KBS CoolFM's "Kang Han Na's Volume Up Radio" in 2020, he revealed that he gets drunk after having a sip of beer.

According to the actor, it could take six hours for him to finish a whole bottle of beer. Despite his confession, fans still think he's an adorable gentleman with a pure heart.

Yoo Ah In

In "Hellbound," Yoo Ah In showed off his charisma and immersive performance. As he appeared in various dramas, he gained a lot of close friendships with many stars.

He can be seen in many get-togethers but fans are curious why most times, Yoo Ah In doesn't drink during gatherings.

The actor revealed that he's not good at drinking. When he drinks, he sees to it that he doesn't go beyond his limit as he turns red very quickly.

Park Hyung Sik

Singer-actor Park Hyung Sik has been in the industry for quite a while now. He is much loved for his unrivaled visuals and perfect physique.

But did you know that he's also a light drinker? In his guest appearance in KBS CoolFM's "Lee So Ra's Music Plaza," the idol-turned-actor admitted that he can only drink one glass of alcohol.

When asked what happens after drinking beyond his limit, Park Hyung Sik says that he becomes as red as a beet.

He also revealed that he had a painful cramp in his leg after drinking one can of beer when he was still a trainee, which undoubtedly traumatized him.

Lee Jin Wook

Unlike the three previously named stars, Lee Jin Wook is already a senior in the industry.

But like the rest of them, he is also one of the artists who can't drink well. In 2015, Lee Jin Wook appeared in tvN's "Three Meals a Day."

He stirred quite the buzz when he confessed that he couldn't drink even a single drop of alcohol because of his very low tolerance.
