请为《瓢虫少女 第二季》这部动画剧集写一段简短且吸引人的故事梗概，包括主要角色及故事背景，要清晰、干脆，能够很好地说明情节及背景，但是不要透露过多剧情内容，结尾应留有悬念。

By daylight, Marinette Dupain-Cheng and Adrien Agreste are ordinary teenagers. But unbeknownst to their family and friends, the two of them carry a huge secret...using the powers of magical creatures called Kwami, they transform into the superheroes Ladybug and Cat Noir! With a mission to protect the city of Paris from the evil Hawk Moth, the two of them must learn to cope with their new responsibilities, as well as ordinary troubles involving love, school, family, and friends. Most of all, they must learn to put their romantic feelings aside in order to perform their duty, unaware of each other's true identities.
