*recollecting my memories.* soo this manga was about this man and girl. the man was like in his 20's? or 30s.(age) and the girl was in her 18-20s around there T^T. and the man was an author/book writer. the girl lived with this man. the girl when she first came to this mans house she was quiet and didnt talk, butt she started to open up later on. i THINK they were uncle-niece not sure. the man's novels were ususally seen as dark or deep or somethinglike that. and later on in the end he wrote a book that was very different from his usual genres.
-in the middle near the end, the man visited his ex to (im not sure) like finish what was never completed? the man and his ex, one time the man locked himself in side the room because it he was depressed?
-the girl loved flowers, the man never really did, but the girl influenced him.
lets see what else i remeberrr....
WELLT HE GIRL AND MAN got together in the end

they had some age gap.
ohhyeaa the man wears a yukata most of the time. mhmhm
