Quick Transmigration: I Got the Obsessive Male Side Character to Fall for Me, Then Checked Out

[Humble transmigrated college student × sickly obsessive male supporting character] Qi An transmigrated into a book, becoming a nameless passerby in a rebirth novel. To stay alive, she desperately tried to win over the sickly male supporting character and make herself noticeable to him. But he ignored her and even threatened her. “Being a busybody isn't necessarily a good thing,” the male supporting character said, staring at her ominously. “...” Heaven help me! I don't want to do this either. I just want to stay alive. “Where do you think you're going?” “I wasn't running...” The man sealed her lips with a kiss. “You can only be mine...” Much later, she lay panting against the man's chest and kissed his Adam's apple ingratiatingly. “...I can only be yours...” The male lead's obsessive nature is mild at first, but he becomes truly obsessive in the middle and later parts of the story. (HE ending. Everyone gets a happy ending.)
