Stem clash (沖)
甲 and 庚 are one of the four stem clashes: they face each other from opposite sides. It is read as two different speeds, which can feel exciting and tiring at once. Saying plans out loud before acting tends to save most of the friction.
Underneath, Metal checks Wood, so 庚 also tends to set the pace.
Both stems are yang: two outgoing, direct styles. Things move fast, and both of you like to decide.

If you are one of them
If you are Yang Wood and your partner is Yang Metal
The element that stands for you (Day Master) is wood, and your partner's is metal. In saju's controlling cycle (相剋, where one element keeps another in check), metal trims wood, like pruning shears shaping a tree. You may find your partner challenging your plans, spotting the weak points and nudging you toward discipline. That can sting, and it can also help you grow in cleaner, stronger directions. You bring warmth and optimism that softens your partner's sharp edges. The key is how feedback lands. Ask your partner to start with what they like about an idea before pointing out gaps. Pruning helps a tree flourish when it is done with care, and that care is something you can openly ask for.
If you are Yang Metal and your partner is Yang Wood
Metal meets wood in your pairing: you are metal and your partner is wood, based on the core element in each person's chart. Saju says metal controls wood, so you likely set many of the standards and boundaries in your shared life. Meanwhile your partner brings optimism, growth and fresh plans that keep you from becoming too rigid. Think of a trellis supporting a climbing rose: structure and growth working together. Tension appears when the trellis feels like a cage. Make room for one area where your partner leads without your input, even if you would do it differently. Trust is the softest and strongest tool you have.

Questions about this pair
Are Yang Wood and Yang Metal compatible?
甲 and 庚 are a stem clash, read as different rhythms rather than a bad match. Many clash couples do well when they plan out loud; the rest of both charts matters too.
Does a 甲庚 clash mean we will break up?
No. A clash marks two stems facing each other from opposite sides, read as different speeds and lots of movement. It is something to plan around, not a verdict.
