After Passing as a Man, I Struggle to Fit Back In with My Brothers-in-Arms

【Dual male leads, showbiz, idols, CP: Xu Cheng'en × Ling Yeshuo, slow-to-realize top × warm on the outside, cold on the inside bottom】I'm Xu Cheng'en, the older brother of the heroine in a boy-band novel where she disguises herself as a boy. Right before our debut, I accidentally injured my foot. To hold on to my debut spot, I asked my twin sister to fill in for me for a while. So I went abroad to treat my foot, and when I returned to the group after recovering, the atmosphere among the members felt strangely off. The leader actually wants to pursue my adorable sister. How dare he? The second-oldest seems like a pervert. He's always playing dress-up games where he raises a character. The third is flighty and frivolous, and often makes people uncomfortable. Good heavens, is there not a single normal person in this group?
