HELP

Okay I have a scenario of a manhwa in my mind but I can't remember which manhwa it's from. It's a historical one. The scene was kinda like the ml and fl probably went on a date at some restaurant. And at the end of their date, they were probably walking on the streets. There was a street lamp which I think lights up rarely and ig it's considered a romantic place among the lovers. Something superstitious like if a couple stands there and the lamp lights up, their love will become successful. I LITERALLY CAN'T BELIEVE WHICH MANHWA IT WAS FROM
