No way, bi people exist, he could have just been a bi guy that got rejected by her brother
But I think she was delusional to think she can seduce his feelings away, but also he actively prepped a whole wedding and took her as his wife, witness and all, so I'm not too mad at her on that point
She's still messy af bcs she never talked it through with her brother and she's a weak ass bitch who let her husband assault her brother in his sleep
I genuinely think she's simply weak of character
And that's why after the divorce and the picture, she didn't try anything on her snake ex, she went after the one guy who's weakest in the narrative
If she had a spine, she would have gotten a restraining order on her husband, for both her and her brother after the whole blowjob situation

The ml is the real villain to me
He lied when he said he was already rejected
Meanwhile they were just fighting
Dated and married the sister, sexually assaulted the brother during that time
Then divorced and ruined the siblings relationship by sending the picture
He's a complete psychopath, he's not normal in the slightest
A real son of a bitch
