Mermaid Omega three and a half years old [Interstellar]

Liao Yan has both human and mermaid bodies, but his mermaid body was accidentally picked up by others.In addition, Liao Yan also found that there was something wrong with his mermaid body.For example, when he became a mermaid, he actually felt that the alpha that picked him up had a very good smell, which made him want to take a bite.For another example, the mermaid's body will suddenly go crazy for a few days every month, which makes him especially want to find someone to hug him.Liao Yan felt that this fish was very abnormal, but when he lost his mind, it would be broken, and he couldn't remember what happened at all.Yuyu Liao Yan pouted his red and swollen lips and asked Kino who adopted him, "What happened, why is my lip so painful?" Kino lied to him without blushing, "You bit it yourself." Yu Liaoyan lifted his shirt and pointed to the bluish-purple marks on his body and asked, "Then what are these?" Kino still lied to him, "You scratched it yourself." Yu Liaoyan didn't quite believe him anymore.Later, when Liao Yan asked his classmates, he realized that Yuyu's reaction seemed to be a sensitive period for omega, and if he was not marked by alpha, he would continue to feel uncomfortable.As a weak omega mermaid, Liao Yan decided to leave Kino, a dangerous alpha.Unexpectedly, Kino said to him: "You can't go, you have already been marked by me, and you are already my omega." Yuyu Liao Yan almost cursed out.Liao Yan had to use his human identity to ask Chino to get the mermaid back.To this, Chino said: I picked it up with my own ability, and it belongs to me.Liao Yan: ... that night, Chino posted a post - the mermaid he snatched is prettier than others.Liao Yan felt that he had suffered the greatest grievance in his life when he saw that the picture accompanying Chino was his fish photo.Note: The article includes that the mermaid set up by the sentinel guide is an adult, but it can act, and only the coquettish fish can eat meat.
