In which game, the female protagonist was considered a servant, while the male protagonist used two identities. One of them wore a mask, while the other identity was a pianist who also suffered from narcolgia?

It was a little old-fashioned. The male protagonist would often play in a secret room until the end and find that there was actually a scar on the male protagonist's face. It was left when he saved the female protagonist when he was young. The most memorable part was the scene of a butterfly flying on a black background. The second male lead liked the male lead. If the favorability was not good enough, he would end up giving the female lead poisoned wine.
