they have different story line and theme but both anime is School, Romance Genre
and here are the other similarities:
Both anime have 2 different class/branch in 1 school, the Normal Branch and the Music Branch for LaCorda and the Day Class and the Night Class for VP
Zero, Yuuki and Kaname love triangle reminds me of the love triangle between Ryotaro, Hino and Len where both Ryotaro/Zero who's the same class/branch with the girl MC is quite cold yet protective with them, while Len and Kaname are both cold, cool, but also care for the girl MC
