It gives you memoirs of a geisha vibes and I absolutely adore it! The female lead lives in a un le and falls in love with the male lead, and starts a journey to find him. I don’t know how the story will end -although there are really a lot of hints- but I suggest that if you are:
Searching a realistic love comic
Female lead stops living in a bubble
Female lead will suffer a tremendous character development
Male lead is hot
Unrequited love possibly
Then read the first three chapters. Read the first chapter
