I Still Sing to You

What is the relationship between Oates and the Verlaine family? He seems to be able to enter and leave the Verlaine family freely, but except for Pierre, he has never seen him interact with anyone else in the Verlaine family. It doesn't look like he has sneaked in, but no one has mentioned him to Pierre. Is he a relative or someone related to him? Judging by their age, Musai is older than Pierre, and they were together when they were children, but they have never seen each other since Oates became Mr. O, or Oates has never appeared in front of Musai in the name of Mr. O. Oates is much older than Pierre... How much age difference is there @_@ It seems that someone didn't know who killed Musset. It happened that Pierre fell ill and needed a heart replacement, so he replaced Musset's heart. From then on, Musset woke up in Pierre's body... Oates, who had been paying attention to this matter, had some supernatural expectations, which was very suspicious. The old man is also very suspicious. If there is a shady secret, the old man probably won't be able to escape, but things may not develop as he wants. CP should be Mousset from Oates x Pierre Piet? If you don't chase a good person, you have to be reborn before you start. Is Mr. Oates an old man? (Beat I haven't started it yet, so I'm just making a bunch of random guesses, waiting for the follow-up =v=

Are there no more updates to such beautiful articles?

Although I read it a little confused, the writing is so beautiful

Excuse me... What is the name of the piece that Pierre was listening to?
