Yes, very much so. "Alpha" is a bullshit term for idiots, quite frankly, and her getting turned on by someone treating her badly (for no good reason, too) makes HER very unattractive in my book. He wasn't even being assertive or anything. He was giving her the silent treatment like a fucking 8 year old when someone doesn't share their toys with them. They're both pathetic.
The MC starts off really bad, snapping at his step mom randomly and treating Myra like she's not a true friend and she was only using him, even though there's no evidence of that and they've known each other for years, made him pretty unlikable too. Thankfully there's less of that as it goes on, though.
Admittingly the scene on the beach was almost cute. But by then it was too little too late.
