Qin Niangzi is a capable adult woman in the 21st century, working diligently at her job every day. Her few hobbies include reading novels and dating the outrageous, tsundere male side characters in them.
She never expected that one dark and stormy night, while reading the latest chapter of The Moonlight Is Me, she'd be so provoked by the tsundere male supporting character that she couldn't hold back the beast within her. She banged on her dorm bed a few times. The bed fought back, knocking Qin Niangzi to the floor and leaving her unconscious.
When she opened her eyes again, she had transmigrated into a book, arriving just before the tsundere male supporting character had met the heroine. And she'd become the cousin he was developing feelings for? Heh... How about having a romance with her before he meets the heroine?~
It feels pretty good~ I hope the focus is not on the house fight, but on the heroine's own life~
