@hacja: I like your take on food based flirting using chopsticks. I hadn’t thought of that!
And, it is never too late. Just get a pair of training chopsticks and you are set!:)

I think this works best when both parties know the cultural nuances of good chopstick work. When my partner and I eat meals with lots of banchan, sometimes I will put a piece of meat on his bowl of rice, obviously in a loving and appreciative way, and I think it's almost entirely lost on him. Even when I have explained, he understands intellectually, but feels nothing about the gesture. Oh well.

@bbstl Since the spork has already been invented, I think we've reached the culmination of eating utensils.
However, if I could follow my usual practice of writing way off topic, I did want to say that the small plates, eaten with chopsticks style does promote a certain culture of eating that might reflect romantic styles as well, and I hope this show might get into food, actually, although it doesn't sound like it will. It sounds like its going to focus on the education aspect. And believe me, as an educator who loves food, cooking is 10 times more romantic than education!

The heart melting gesture of @jls943 -- your partner may deny that he is aware of what you are doing, but I am sure its like the chaebol pretending not to notice the beautiful and charming actress who is the female lead--would not be possible for me in my house, because my wife would have already eaten the piece of meat even before I sat down and looked around for more. But that's exactly why we are so compatible--the first meal I cooked for her involved a huge prime rib and a big tub of garlic mashed potatoes. My only misfire was the pie and ice cream for dessert--turns out she doesn't like blueberry pie--but by that time she was too full to walk out on me. So I successfully followed the overstuffing theory of food romance, and have ever since!

I think banchan stores must be pretty common. I think Memorials had a scene where the ML compliments the FL's mom's food only to find out she bought it from a banchan place 😂.
