After Miyamori, (along with Ichika) is sent to question about plagiarism her ad, Ichika interjects and defends her by revealing that the blog itself that is now gone could have posted their false date of five years ago, meaning that the article claiming plagiarism is completely fake,
but the company are cowards in thinking it'd be easier to just write an apology without wasting time and money on revealing that truth.
Afterwards, they ask Miyamori to confirm an old video of hers that surfaced.
Showing her as a high schooler, where she destroyed a homeless' home.
As the video plays, Miyamori panics in hyperventilation, which causes her to faint.
In her panic, we hear glimpses of the people who criticized her life for this, and once more a glimpse of a probable bully friend who somewhat manipulated her to do this.
The same woman who we saw in the previous chapter. The one who made this fake plagiarism claim.
