We have to agree to disagee here, the same scene will come across differently to different viewers.>His Mom
A failed manipulation, to me her obvious dislike for Hiromi at the beginning of the series made me believe she said what she did to drive a wedge between her son and Hiromi, to stop a possible relationship between them.>Hiromi
Most of the scenes between her and Shin came across to me as her trying to tie Shin to herself by making him feel guilty (the sudden kiss, inviting him to her room then acting emotionally weak and hurt). >Noe
"Write it down" was more childish than manipulative from my point of view. Most of her scenes involved her and Shin supporting each other rather than one using the other as an emotional crutch.
