Promise - LSZ x LJY fanfic

Summary: Lan Sizhui and Lan Jingyi, together with their fellow GusuLan sect disciples, were tasked to go to the Mo Village to exterminate the walking corpses plaguing the town. However, they met an accident. One, an evil arm appeared. Two, a strange feeling within them appeared. They kissed when they fell on each other... literally and figuratively. (A/N: the first ZhuiYi fic I made scratched my tender heart and so I made this! I hope you'll like it! This will be short though. Also...I feel like my soul is being purified as I write this story!)
