The Twin's Identity Theft

Summary

After my husband died, his twin brother's personality suddenly changed drastically.

The originally silent and steady man suddenly became sunny and loved joking.

He used to treat his beautiful sister-in-law like an old married couple, but recently swept away his reserve, lights in her room staying on all night.

During the day, he shamelessly held hands and hugged her waist in front of people.

Until that night, he groggily entered the wrong room after using the bathroom and climbed into my bed.

Suddenly approached by a familiar body, I finally saw through him.
