Lin Yanjun was selfish and cold. He did not care for much except himself and his rap, and he definitely did not care for chubby boys that trampled on his feet in the middle of dance practice. You Zhangjing was dramatic and loud. He made easy friends with almost anyone, except for narcissistic, judgmental, disrespectful, incorrigible, condescending - Well, except for Lin Yanjun. [a/n this is on AO3 but i'm putting it on here bc why not]
