Stem combination (合)
乙 and 庚 form one of the five stem combinations, which the tables say turns toward Metal. It is read as a strong pull: you notice each other, and working as a team comes naturally. Keep your own interests too, so the pull stays a choice.
Underneath, Metal checks Wood, so 庚 also tends to set the pace.
One yang stem and one yin stem: one tends to push forward and the other tends to read the room, which often fits well.

If you are one of them
If you are Yin Wood and your partner is Yang Metal
With wood at your core facing your partner's metal, this is a pairing of growth and precision. Saju reads metal as cutting and shaping wood, which means your partner may naturally set boundaries, deadlines or standards in your shared life. You bring flexibility and fresh ideas that keep things from becoming rigid. When it clicks, you are like a carpenter with a sharp chisel: capable of beautiful work. When it does not, you may feel boxed in. Let your partner know where you want structure and where you want freedom, maybe in writing. Clear boundaries make metal's gift feel like support instead of restriction.
If you are Yang Metal and your partner is Yin Wood
In your match, metal meets wood. Your core element (日干) is metal, your partner's is wood, and in the controlling cycle (相剋, how elements balance each other) metal refines wood. You may be the planner, editor or disciplined one, while your partner is the dreamer and starter. Picture a carpenter's chisel and a fine piece of timber: skill and potential together create something lasting. When it tips, your partner may feel their enthusiasm is cut short. Try praising the idea before you examine it, and keep your first response to a question rather than a correction. That order keeps your precision helpful and their spirit intact.
