Synopsis
Airi, my brother’s wife, is beautiful but cold toward me—someone I’ve always found difficult to deal with. One day, while watching adult videos in my room, she suddenly walks in. Surprisingly, she doesn’t leave and ends up watching with me! That night, she comes to my room saying “You owe me for keeping me awake///” and we cross the line. Our secret lover relationship begins! Is her tsundere attitude around the family just to hide it from her husband? Or merely shyness? A completely subjective view of our forbidden relationship—taboo infidelity with a sister-in-law who can’t be honest with herself!
