"After It Was Ruined, Senior Sister's System Collapsed"

The Male Protagonist Began to Have a Crush on His Senior Sister, and Later Fell in Love with the Female Protagonist, and He Began to Cultivate Immortality and Immortality.

The Male Protagonist Realizes That He Doesn't Love the Female Protagonist and Falls in Love with the Vicious Female Partner Who Is Rich and Beautiful and Loves Him.

Is There a Female Version of the Wife-Chasing Crematorium?

I Begged the Second Male Lead to Fall in Love with the Original Heroine but Couldn't Find It, and the New Heroine Redeemed Me (Yandering Second Male Lead)

I want to read a book similar to "If You Can't Fall in Love Through a Book, You Must Win the Dark Room".
