As TRP is amoral, what are the best ways to make women invest in emotions?

In other words, to make them attached to you.

Yes, sex is the first thing that comes in my mind, but I’m sure there are other ways to do that prior to sex in my opinion.

I noticed that letting them talk about things they like make them slightly more invested. Probably because they are receiving hormonal spikes (Serotonine I guess) while thinking about positive things they like in their life, such as hobbies etc.

Another thing is letting them do stuff/giving them orders. “Can you give me a cigarette” or “Sit here”.

Or basic push and pull I guess? You make them feel like you like them while another day you totally ignore them.

I believe making them invested is crucial to make them attracted to you. Actually, women play the same game with betas.
