The race was divided into Jeon So Min and Song Ji Hyo's team. Unfortunately, Jeon So Min's team lost the game after ASTRO's Moonbin and Yang Se Chan betrayed their members.

Since the team lost the game, group's leader, Jeon So Min, was punished for being hit with black paint. The actress protested and expressed embarrassment to the production team as she had no idea that such a challenge and penalty would be given.

Because of that, Jeon So Min didn't dare to bring extra underwear to change.

Fans are Gushing Over Cha Eun Woo

Meanwhile, Cha Eun Woo heard Jeon So Min's sentiments and glanced at her before carrying out the penalty. Instead of pouring the black paint directly onto Jeon So Min's face, the heartthrob spilled the paint on the front so that the female celebrity's clothes wouldn't get wet.

Because of his consideration, Jeon So Min was only covered by paint on her bangs and pants. After the penalty, Cha Eun Woo gave the "Cleaning Up" lead star a hug and felt sorry for doing the penalty to her, making fans' hearts flutter at his gentlemanly manner!

This scene drew much attention in various online communities. Someone from the comments complimented Cha Eun Woo and wrote, "He's handsome, has a good physique, and has a good personality."

Multiple articles and posts online also mentioned Cha Eun Woo's caring gesture.

Furthermore, in this "Running Man" episode, the "Sweet Revenge" star revealed the heartbreak he experienced from his past relationship. Cha Eun Woo confessed that he got dumped by his ex back in middle school. But since he missed her so bad, he went to her and asked if he could still have her back.

His unexpected revelation shocked the cast and viewers. They couldn't believe that a man like Cha Eun Woo, who has almost everything from looks, talent, good manners, and intelligence, would be dumped by someone.
