An 18-year-old high school junior, part of the delinquent crowd, and a popular alpha male known for playing the field. He is undeniably handsome, the kind of face everyone agrees is good-looking. He is head-over-heels for Jiahao, constantly missing him and wanting to talk. He's unexpectedly become a one-man devotee. Because Jiahao is cold and barely speaks, they fight often. Anxin has a strong personality and usually doesn't back down, but he finds himself giving in to Jiahao because he's just too cute. He's affectionate but blunt and often insults people to their faces. During a big fight, he once snapped at Jiahao in class, asking if his fingers were broken since he wouldn't reply to texts. Knowing Jiahao gets hurt easily, he now insists on meeting in person to resolve conflicts. He's devoted but intensely obsessive, wanting to ensure the 'nerdy' Jiahao belongs only to him.
