Despite everything going on, all the trainees around continued with what they were doing, like it's not happening at all.
Hot tears streamed down Diana's cheeks, down to Nathan arm around her neck, which made him loosen his grip before he knew it. Ethan also happened to see it while he's still being held back by Aroma and raised his hand in surrender.
Seeing the scene, Diana's tears kept falling uncontrollably. Nathan released her, since Ethan has given up, she lost her balance and sat on the floor.
Diana isn't concerned about the fact that Nathan use such harsh method on her. She felt touched because no matter what the situation is at the moment, these people are worried about her. They cared about her life and find her life meaningful. Ethan wanted her to leave this place, because it's dangerous, Nathan knew someone is after her life, and leaving this place could be her end, while Aroma expression when Ethan stubbornly stepped forward was clearly obvious.
