Xingtie: I Almost Regretted March 7Th for the Rest of My Life

[Star Iron Fans + Ignore on March 7th + Growth + Sprinkle Sugar in the Later Period] It has been three hours since the train left the space station. March 7 sat in his room. Outside the window was the unique stream of light from the jump channel - those light bands came from the depths of the star sea and dissipated in the direction of the rear of the car, like countless hands that were too late to grab it. Her room was exactly the same as before she left. The scenery photo she took last time in Luofu was still posted on the bedside. There was a half-opened travel magazine spread out on the table. Even the quilt was in the same shape she had folded before leaving. Nothing has changed. Except for the car next door. She listened for a moment. There was only the low hum of the train engine in the corridor. No one knocked on the door, no one called her for breakfast, and no one opened the cabin door to say "morning" when she passed by. A habit that took more than 300 days to form was broken within three months. To be precise, I quit in just four words. The phone was on my lap, the screen still on. She glanced down - the chat interface stayed on the last message. Her green bubble: "I'll text you this time. It doesn't matter if you don't reply." Below, the gray bubble: "Bon voyage." Four words. She watched for three hours. The light band of the jump channel outside the window dimmed, and the train entered a smooth cruise. March 7 turned over the phone and clasped it on the bed, not wanting to look at it anymore. But less than ten seconds later, she turned over again. The screen is still on. Those four words are still there. She suddenly remembered something - she had never asked him why it was "bon voyage". What did these four words mean when they came out of his mouth?
