The next morning, Dr. Ben tells Cai that he can't even tell Cai what happened the night before. Cai asks if he's serious about what he said yesterday, and he says that he is happy and fortunate that he has met Cai. Cai tells him that he went to rebirth X to investigate his mother's research, which is similar to his father's. He says that the research team at rebirth X has a different kind of research than the one that Cai's father is involved in. He went to approach Cai to see if he would be interested in becoming a part of the team. Cai says that when he first approached Cai, he was told that he was not welcome, but when he found out that Cai didn't like him, he had to break off the relationship with Cai so he could continue his research. Cai explains that he had already been with Cai before, but that he took advantage of the feelings that Cai had for him. He also says that this heart is very important, because otherwise, Cai wouldn't be able to destroy all of the research.
