Kim Hye Soo shared several behind-the-scenes photos from the set of 'Signal Season 2' on her social media, captioned simply, “#ThankYou actor Lee Donghwi.”

The photos show Kim posing in front of a coffee truck sent by Lee Dong Hwi to support the cast and crew.

Dressed in a lightweight knit top and sleeveless pants, she embodied a cool and relaxed summer look. Her outfit, completed with a tone-on-tone cap and nearly barefoot sneakers, gave off a breezy and comfortable filming atmosphere.
In one shot, Kim playfully points to the coffee truck’s banner with a cheerful expression, catching fans’ attention with her signature charm. The banner read, “Cheering on actors Kim Hyesoo & Lee Jehoon and the entire team of ‘Signal Season 2’!” — showing Lee Donghwi’s heartfelt support.
Across the cuts, Kim’s expressions reminded many of her iconic role as Cha Soohyun—as if the character had stepped into real life. Even after nearly a decade, her presence remains undiminished.
Kim Hyesoo is currently filming 'Signal Season 2', reprising her role as detective Cha Soohyun. The drama is scheduled to air in the first half of 2026, marking her long-awaited return to the role after nine years since Season 1.
