I think it's an Asano Taeko trope. No one can ever just move away. In Last Friends the abusive boyfriend killed himself and left his body for his girlfriend to find... the morning after he raped her... draped under a wedding dress he'd bought her.

Poor Subaru could be a publicist the way he tries to spin things. XD

(Am going to watch IRIS now -- pain meds knocked me out earlier -- I'm so excited!!! Hyun Joon, come to mama!)
