Wait, where’s the part where he dies under the protagonist’s sword? How did it become rolling under the protagonist, being done by him? This… this… this situation’s too embarrassing?!…In a dense forest, Su Yang holds a sword to Gu Feidi’s throat, speechless dismay in his eyes.Su Yang, extremely confused: I have recited all my lines, where is the person in the script that would come to his rescue???Gu Feidi, emotionally moved: He could have killed me, but he hesitates to make the move.In the wasteland, Su Yang blocks a fatal blow aimed at Gu Feidi.Su Yang, enraged: Motherf*cker! If he dies now, who wold kill me and send me home!!!Gu Feidi, worried: He’s willing to give up his life to save me.In a cave, Su Yang watches over Gu Feidi’s cold sweat from poisoning.Su Yang, distressed: The female lead’s run away, who’ll detoxify him by mouth-to-mouth?!Gu Feidi, in anticipation: Why hasn’t he kissed me?
