"No! Marian won't leave me!"
Despite Baki's efforts to dissuade him, Achard, as if mad, rushed back to the old Eden Hotel, only to discover that Mr. Schumann, Marian's brother, had already left.
He retrieved an invitation from the gap under the door, then noticed there was a letter behind it.
The letter was written by Miss Marian, and its main content was that she had decided to prioritize her family and had accepted Mr. Bourget's marriage proposal, as well as wishing Achard happiness and so on.
It was a very pragmatic choice. Although she was once captivated by Achard's charm and erudition, he was, after all, just a "poor vegetable farmer." Coupled with her brother's statement that he would not provide a dowry if she married him, in the end, she chose the wealthy merchant Bourget.
