【Single Female Lead · Book Transmigration · Light-hearted Sweet Romance · Professor Sister · Cold Outside, Warm Inside · Motherly Girlfriend · Song Copying】

One morning, Jiang Yichen wakes up and discovers that the world he is in is the same as a yuri tragic romance novel he once read in his previous life.

One of the original heroines is his own older sister.

The other heroine is named Qin Ling.

A ruthless woman that even a dog passing by would want to slap twice.

“Sis, listen to me. You really need to stay far away from that Qin Ling...”

In a milk tea shop, Jiang Yichen is trying to warn his older sister.

He has no idea that Qin Ling is sitting right behind him...

PS: No yandere, just an ordinary romance novel. The female lead is a cool and gentle older-sister type.
