Yes it actually did, Im not sure if it was in the main or side story tho
Spoiler
Yes, we get to read in the novel about how her parents were going through her stuff and cleaning since her death, and finding out how poorly and humbly she lived..and finally (too late made i add) they see her for how she was, a really good daughter that didn't have the support and love she deserved...is kind sad, and regrettable. But she get to see them in a dream i think..or it was included as a short side story...
What happened to her brother?
Also spoiler :)
He got scared but before he ran away he stole her money from the purse. Withdrew money and went on gambling spree. But fortunately police caught him and he was awaiting trial when FL was seeing glimpses of what happend.
Also her cheating ex regreted what he did. There was short info that he quit his job and was drinking away. Since if their date went on as planned she would still be alive. At least that day...
Do you know what happened to Jina in her world? Since her brother pushed her and she died. Did the novel ever go through the aftermath of it?
