Slow-on-the-uptake, straight girl x lovesick yandere
Yu Zhi transmigrated into a random side character in a male-oriented power fantasy novel.
She was one of the many female side characters who admired the original male lead early in the story. Out of jealousy, after he took a fellow disciple as his personal student, she pushed that disciple off the Kui Ghost Cliff to be devoured by evil spirits. She was ultimately expelled from her sect and met a cannon-fodder's fate.
Yu Zhi's response: Pack up and get out of here.
But before she could leave the sect, the new lazy male disciple seemed to have a crush on her. To avoid her cannon-fodder fate, Yu Zhi went straight up to him and asked, "Would you like to be my cultivation partner?"
The lazy male disciple smiled. "Sure."
Yu Zhi, later on:
A fully automated recorder capturing all the classic romantic moments between the original male lead and the beauties around him. Whether the heroine gives him a heart-shaped gift, and she cheers him on; a supporting girl cries, and she hands her a handkerchief; or the original male lead gets so furious his qi and blood surge, she munches on sunflower seeds...
She enjoyed the show, but her lazy cultivation partner was so clingy that he insisted on spending all day pressed against her, and every so often he'd say, "They're so annoying. How about we kill them all?"
Yu Zhi rested her partner's head on her shoulder and said sweetly, "Kisses, kisses. Be good and look at me."
