[Single Female Lead] [Transmigration into a Novel] [Lighthearted Romance] [Professor Sister] [Cold Exterior, Warm Heart] [Motherly Girlfriend] [Song Plagiarism]

Waking up one morning, Jiang Yichen realized that the world he was in was the same as a certain tragic yuri novel he had read in his past life.

One of the original female leads in the novel was his own elder sister.

The other female lead was Qin Ling—a ruthless woman who would slap even a passing dog twice.

“Sis, listen to me, you have to stay away from that Qin Ling…” In a milk tea shop, Jiang Yichen earnestly warned his sister.

Little did he know, the very Qin Ling he was talking about was sitting right behind him…

P.S.: No yandere, just an ordinary romance. The female lead is a serene, gentle, and mature older sister.
