I'm Awesome! The Game Invaded, and You Made Me Invade Yanderes?

[Yandere] + [possessive] + [one heroine] + [urban slice of life]

A yandere game called Love has invaded Yang Qing’s phone. Xue Qianhe, the perfect virtual lover from the game, suddenly appears everywhere in his real world, enveloping him with her suffocatingly sweet smile and pathological need for control. To send her back to the game, Yang Qing has no choice but to indulge her twisted desires again and again. Each time he completes one of her obsession quests, her temperature drops a little, until she disappears completely. But when he completes the final quest, “Make Yang Qing belong to me forever,” Xue Qianhe leaves him with a warm kiss:

“I lied. I never planned to go back.”
