Suddenly Li Chang got angry and he punched Reo and he took his collar and said, "I told you to stop."
Reo angrily punched back at him and asked, "Who are you to tell me to stop. Li Chang don't act like you own her."
"I own her. She is mine only. I won't let anyone have her," Li Chang said and that face was something scary and that every sentence of his was with a strong feeling. That feeling has the meaning of projecting about the real Li Chang who was in love with Reel for a long time and he started to realize it when the fear of losing came to his mind. He was living with a lie. Reo's sudden appearance let that lie out.
Li Chang was not sure with his own feelings. One side he was happy to find out he is going to be a father and another side he is getting jealous about Reo and Reel. He didn't realize that he wanted Reel on his side and that he wanted his baby too. But that seems pretty troubling.
