The Cannon Fodder Male Supporting Character Was Topped by the Female Lead’s Brother

I transmigrated into a sweet romance novel as the cannon fodder male supporting character. According to the plot, I drug the female lead, and then the male lead arrives and kicks me, breaking two of my ribs. But when I opened the private room door, I found that the female lead, who should have been there, was nowhere to be seen. Instead, the female lead’s brother was lounging on the sofa, casually holding the drugged drink. Hearing the door open, his eyes locked onto me. Then he tilted his head back, downed the drink in one gulp, and asked with a smile: “Aren’t you going to run?”
