When the Locust Flowers Bloom

Huai Meng is the existence of Ou Yue's "first love". Time passed, and they were admitted to the same school, but Huai Meng no longer remembered Ou Yue. So, although Ou Yue remembered Huai Meng, she pretended not to know each other and lived campus life together. Later, due to a mistake, Huai Meng woke up in Ou Yue's house, with butterfly wings on his back and turned into an elf.
