Here we go:
The news of Kaoris pregnancy first broke to Kōusei Arima Who recieved a phone call from Doctor Parry whilst practising piano.
"Hello this is Kōusei, Who is this" said Kōusei
"This is Doctor Parry..." said Doctor Parry before being interrupted
"Is Kaori going to be okay" said Kōusei
"She's fine, although I have some very important news for you" said Doctor Parry
"What is it" said Kōusei
"Your going to be a father" said Doctor Parry
"I don't believe it" said Kōusei
"Well we did DNA tests on the baby inside Kaori and it registered you as the father" said Doctor Parry
Kōusei Soon smiled and laughed and said "Thanks doc, this may be one of the best days of my life" as he hung up the phone
