Im (壬) and Gye (癸) Compatibility: The Sea and the Rain in Korean Saju
Im (壬, Yang Water) and Gye (癸, Yin Water) are the sea and the rain: the same water in two forms, endlessly feeding each other. They understand each other's moods and instincts with unusual ease, and they also measure themselves against each other more than either likes to admit.
The elemental dynamic
The relation is the same element with opposite polarity. Im is the big body of water: river, tide, ocean, moving outward and visibly. Gye is water in its finest form: rain, mist, dew, underground springs, moving quietly and getting everywhere. Rain falls into the sea; the sea evaporates and becomes rain again. It is hard to think of a closer elemental bond.
Closeness has a cost, though. Two Water stems together amplify Water's traits on both sides, the intelligence and adaptability as well as the worry, secrecy and tendency to drift. A Water-heavy household may need conscious grounding, which classical texts would describe as Earth for banks and Fire for warmth.
How each sees the other
The roles are mirror images: Im sees Gye as Rob Wealth, and Gye sees Im as Rob Wealth (겁재, 劫財, geopjae).
Rob Wealth is the peer star of opposite polarity. It brings courage, drive, risk-taking and a competitive edge, along with loyalty when it counts. Compared with Friend, which is the same stem mirrored, Rob Wealth is the sibling who is similar enough to compete with and different enough to surprise you. Im sees in Gye a subtle strategist; Gye sees in Im a bold operator. Each quietly thinks it could do the other's job.
In the traditional gendered reading, Rob Wealth for a man is said to take from Wealth, his classical wife star, so older texts link it with rivalry over partners or money. For women it is read more broadly as a competitive peer. The neutral reading is the useful one: equals who push each other hard, especially over shared resources and credit.

Combination or clash
Neither applies between them. Im combines (합, 合, hap) with Jeong, and Gye combines with Mu. Their stem clashes (충, 沖, chung) are 丙壬 for Im and 丁癸 for Gye. So no 合 binds these two and no 沖 sets them against each other.
A quick aside for those who like the mechanics: Jeong (丁, Yin Fire) sits in both lists, as Im's combination partner and Gye's clash partner. A Jeong year or a third person with strong Jeong energy may therefore pull Im closer while unsettling Gye. Practitioners vary in how much weight they give this between two charts, but it is a good reason to watch outside timing in this relationship.
In love
Emotional fluency is the gift. These two read each other's silences, finish each other's thoughts and adapt easily to travel or change. The friction comes from competition: who is cleverer, who controls the money, whose friends get more time. Arguments can be indirect, conducted through hints and moods rather than open words.
At work
Good for strategy, finance, research, communications and anything requiring intelligence and flexibility. Im handles public momentum; Gye handles behind-the-scenes analysis. Partnership agreements should spell out ownership clearly, since Rob Wealth is the star most associated with disputes between partners over money.
Making it work
Agree on money early and in writing. Turn the competitive streak toward shared goals instead of each other. Speak directly rather than through hints. Bring in grounding influences, a routine, a garden, a regular commitment, to keep two currents from scattering.
