K-Actor Woo Do Hwan is stealing hearts for the adorable way he treats co-star Lee Yoo Mi.

Woo Do Hwan's Sweet Gesture for Lee Yoo Mi

In the new K-drama "Mr. Plankton," Netizens took to social media to praise Woo as a gentleman ever since Netflix Korea unveiled a video clip of the behind-the-scenes on Nov. 13.

In the video, set against the backdrop of a picturesque rice field, both stars depict figures ensnared in a melodramatic moment. The cameras roll one minute, and the next, they are on the grass, playing, fighting in the sun.

However, viewers were most moved by seeing Woo Do Hwan pick up Lee Yoo Mi and carry her across the wet grass onto the tarmac.

It was regarded and interpreted as a gesture of care so that Lee would not get uncomfortably wet after the shoot.

Shortly afterward, online fans showered Woo Do Hwan with praises, calling him a "gentleman" and commending his thoughtfulness.

One social media user commented, "His sweetness, especially the way he treats Lee Yoo Mi, is just so endearing."

"These are the tiny moments that we love even more about him!," another commented.

This show has already captivated audiences with its plotline, and its lead actors have been experts at blending a little reality with the fictional "Mr. Plankton" to keep the emotional rollercoaster rolling in real life.
