After Rejecting the Campus Belle, I Picked Up Frolova

[One heroine + Frolova + transmigration in the opposite direction + yandere]

After getting blackout drunk at his high school graduation party, Jiang Xiangsheng went home. The next morning, he woke to find a girl with dark green braids curled up in his arms, looking exactly like Frolova from the game Wuthering Waves.

But this Frolova wasn't quite that Frolova. She was a blend of the game character and the fanfiction he had written, a girl who belonged only to him and loved him deeply.

Note: Frolova's characterization may be out of character.
