Firstly because I have gotten so sick of Mike and Lucy's bullshit that I don't WANT to see them happy. Taeshi pulled that trick too many times and now Mike or Lucy doing anything different would itself be unbelievable; if nothing thus far has inspired them to move on and grow, nothing will. The relationship drama already had a near-death experience, multiple confessions/rejections, suicide attempt, cheating, and tearful apologies. There's no more room to escalate.

Secondarily, I like Sandy as a character and want her to be happy; if it's at the expense of the main 4 that's all the better.

And due to those two reasons, I find the idea of Sandy mindbreaking Mike/Lucy/Daisy/Paulo through her sheer superiority both funny and cathartic.
