Dang E Yi Yu Dao Bing Jiao

A yuri story about a yandere commoner × villainess lady. When the arrogant noblewoman He Sha tried to bully the commoner girl Qiao Lin out of jealousy, the yandere Qiao Lin turned the tables and took her first kiss instead. At first, He Sha just wanted to get back at Qiao Lin by playing pranks on her, but eventually it became an excuse to try to attract Qiao Lin's attention… The more the villainess tries to mess with the yandere, the more the yandere returns the favor, which only makes the villainess more tsundere.
