Loving with My Mind LWMM

Married accordingly and conveniently, she was prepared to be tied within a loveless relationship. She had nothing to lose anyway.

He obediently shackled himself, not bothering to take a second look at her. He just signed the papers, got into the venue and let everyone take photos.
She was not an eyesore, but they were only civil, at times pretentious.

If loving can only be done with the heart, is it impossible for someone to learn it?
