All the explanations of the screenshots are below the text.

The context for the Nerd screenshot is that:
— He sent provocative images to another woman while still in a relationship with Kowasu. He didn't see it as an issue at the alter that sent it had no intention of dating in Kowasu's system.

These are both screenshots from Kowasu's twitter where shi states that shi is: a lesbian & that shi doesn't love Nerd.
Nerd has apologised for "cheating" but Kowasu & friends (such as Alice) have a stalking problem.

I have no context for the 2nd screenshot as it was just a conversation in MTP about ex-partners. Nevertheless, it was posted unconsentually.
