So there's a girl I'm courting/dating right now, and were both Kdrama addicts. Many of us have seen or known of Green Flag behavior/acts on Kdramas several times. Since I haven't watched all of them, can you please help me and write them down in this forum post?

Behavior/Act:
Who:
Drama:
Episode (with timestamp if possible):

Since this might count as spoiler content, can you blur/spoiler tag the Behavior/Act and Episode if necessary?

I plan to learn about them and apply them in real life if possible HAHAHA. I want her to fall in love with me, and I also want to be that green flag guy for her.
