My Senior Brother Is from Carrot Planet

I am currently a first-year PhD student in molecular biology at a medical university in China. Okay, I admit that I am a female doctor, a single female doctor. Normally, all my experimental subjects should be white mice. However, due to hormonal disorders, I secretly collected the hair of a handsome senior brother in the same laboratory and conducted DNA sequencing analysis. All the horrifying events started from the moment the sequencing results came out... The results showed that the senior brother was actually an alien?
