It has been some time since Dan Heng and Stella were released from the House of Shackles. During the attack on Stelle, Dan Heng managed to react in time and push her away, saving her life. Then he felt the pain in his chest again from the realization that he could lose his dear comrade. In fact, the situation when they were locked inside the House of Shackles brought them closer together, because they could only interact with each other, except for Hanya and Moze. A new look at his relationship with Stelle and the moment of mortal danger, even if it flew by, began to cause Dan Heng nightmares upon returning to the Star Express. In a bad dream, he saw scenes of how he did not manage to push Stelle away in time, and she died. This caused Dan Heng to wake up in the middle of the night in a cold sweat, breathing heavily. Despite his attempts to convince his inflamed brain that Stelle was all right, the nightmares would not go away and tormented him. On one of these nights, when Dan Heng, tired, pale and sleepless, with pronounced bruises under his eyes from lack of sleep and nervousness, was sitting on a futon, and an azure-colored blanket casually covered his legs and part of his torso, there was a knock on the Archive door. He did not understand who could need something from him at such an hour, and sighed softly, saying a slightly hoarse and calm "come in."
