Start from Love Apartment

This is my first time writing a book and I don't know how to write it. If the writing is not good, please give me some advice. When the doctor was reborn again, he came to the love apartment. What kind of sparks will all this create? Can the Doctor get over the guilt of that war? Can the brilliance of humanity revive the Doctor and undo the mistakes of the Time War? What kind of story will happen to everyone in the love apartment together with the doctor? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
