Regarding the ending with Season 2 in mind

As soon as I read the script, I thought of Season 2. Hee-ju buys a winery and lives the new life she always wanted in France, but it isn't quite satisfying. This is likely because the best experience of her life was the trip to France with Do-kyung. It feels like she has gone to the place that was the most brilliant light of her life. However, since the uninvited guest Cheong-gang (Kim Min) followed her, I had doubts about whether Hee-ju would be able to spend this money wisely and live happily in the future.
