If Luoz felt nothing at the beginning, how can he possibly feel nothing now, given the way things have progressed? Even though he doesn't know why Vivian is acting so bizarrely, he knows it has to do with Zheng Haoyu, doesn't it?
A strange emotion suddenly occupies his heart. Luoz's kisses become fierce. He may love Su Nian, deeply in love with her, but he is a person, not an unfeeling animal. He feels very uncomfortable being used by Su Nian as a shield against Zheng Haoyu.
The kiss gradually changes its nature. Luoz, as a man, becomes dominant. Su Nian's body softly clings to him. She's running out of breath, yet her consciousness remains clear. 'Luoz, are you angry?' she wonders.
Her body is increasingly weak. She no longer has the energy to care about the cold light in the high-rise building. Right now, breathing seems to be the most important thing!
