Viewers charmed by Seo In-guk's understated engineer flirting

tvN has released a compilation of the low-key flirting between the engineering characters in its drama (내일도출근), with moments spanning a robot vacuum and a repair shop. In the comments, the most-liked reaction centered on Seo In-guk's character, Kang Si-woo, playing on his knack with machines: "Manager Kang Si-woo, who says he's never lost to a machine, doesn't seem to lose at kissing either lol — he's so good" (기계에 진적없다는 강시우책임 키스에서도 진적 없는듯ㅋㅋ 너무 잘함). Another widely-liked comment read, "Seo In-guk makes me smile," describing the scenes as fluttering. Several viewers singled out the kiss itself, with one writing, "Being an engineering student, his lines are concise, but the kiss — wow, it's intense."

Other commenters latched onto the "engineer flirting" framing, calling it logical and charming. "The compilation is really good; Kang Si-woo is a fox," one wrote, part of a recurring fox motif that ran through the thread. "It's an explosion of flutter for the first time in a while," another said, while others simply called the scenes "so sweet." A few pointed to specific details: one noted the tango music that plays as the character comes home, saying "when he rides the rhythm, it's great," and another admitted, "Engineering flirting is charming; I'm an arts major, so I never knew." Impatience surfaced too, with comments like "What do you mean, wait? I can't wait."
