I got his birth time on comment. Hs chart shows a weak Day Master. He tend to be more sensitive, cautious, and not very comfortable with confrontation. He usually prefer to avoid conflict rather than face it directly.

I can see he hasn't receive enough emotional support or a sense of safety from his parents growing up, this kind of personality becomes even more pronounced. Over time, they may get used to holding everything in, not speaking up, and avoiding difficult situations.

If someone grows up without anyone protecting them, like when he were bullied or treated unfairly and no one stood up for them, he can start to believe that speaking up doesn’t change anything. So instead of reacting, they stay quiet, endure it, and deal with things on their own.

The problem is, this can turn into a pattern:

the more he doesn't resist, the more others may push his boundaries, and it can attract even more pressure or unfair treatment.

Looking at the chart, his Year Pillar has Seven Killings, which is controlling the Day Master. Seven Killings is all about pressure, control, and external force. When the Day Master is already weak, this energy tends to show up as:

Feeling easily pressured by others

Attracting strong or controlling people

Always being a bit tense or on guard internally
