Ji Sung × Lee Bo-young BaZi Compatibility: Mutual Spouse Stars, Zero-Scandal Model Couple Locked Together by a Day Pillar Clash

Ji Sung and Lee Bo-young are famously known as the 'zero-scandal model couple' in the Korean entertainment industry. They quietly married in 2017, have one son and one daughter, and almost no negative news can be found about them outside of work. When their BaZi charts are compared, the conclusion is clear: this is a compatibility chart full of highlights—they truly are each other's 'mutual spouse stars.'

Ji Sung's Day Master is Yi Wood, which is exactly Lee Bo-young's husband star; Lee Bo-young's Day Master is Ji Earth, which is exactly Ji Sung's wife star. The Day Masters of the two are precisely each other's 'true spouse star'—this is the most direct signal in compatibility analysis that 'you are the one I am looking for.' Add the Year Stem Ding-Wu generating cycle, Year Branch Si-Wu half Fire combination, Month Stem Ren-Yi generating cycle, and Month Branch Yin-Chou hidden combination—from Year to Month, all generating and hidden combinations. The grade falls at medium, with the only challenge being the Day Pillar Yi-Ji overcoming cycle—but this 'overcoming' is precisely the relationship of mutual spouse stars, a tension that requires careful management yet also makes each other most important.

First, Look at Their Charts

Both have only three pillars publicly known (hour pillar unknown), but the Day Master, Ten Gods, and spouse palace (Day Branch) are unaffected by the Hour Pillar, so the main compatibility analysis still holds. The two tables below leave the Hour Pillar blank.

Ji Sung (Male, 1977-02-27) Day Master: Yi Wood.

Lee Bo-young (Female, 1979-01-12) Day Master: Ji Earth.

Why Are They So Stable in Fortune Analysis?

The highlight of this couple centers on one key term—mutual spouse stars. Let's break it down point by point, all based on objective comparison of their actual charts by the algorithm, not human judgment.

Spouse Stars: Each Other's Day Master Is the True Spouse Star

According to the formula, a man's wife star = Wealth = the element his Day Master overcomes; Yi Wood overcomes Earth, so Ji Sung's wife star is 'Earth.' A woman's husband star = Officer/Warlord = the element that overcomes her Day Master; Wood overcomes Earth, so Lee Bo-young's husband star is 'Wood.'

Put these together, and the beauty is here—Lee Bo-young's Day Master is Ji Earth, exactly Ji Sung's wife star; Ji Sung's Day Master is Yi Wood, exactly Lee Bo-young's husband star. The Day Master elements of the two stand precisely on each other's 'true spouse star' position. In compatibility analysis, this is called mutual spouse stars, the most direct and strongest signal of 'being able to become spouses': not just general compatibility, but the chart's foundation marking the other as 'the one to marry.'

Many charts that seem very compatible have spouse stars pointing to a third element—attraction exists but marriage doesn't happen. This couple is the opposite: their Day Masters lock onto each other, which is the fortune-analysis basis for their long-lasting, low-key relationship that prioritizes family.

Day Master Relationship: Yi Wood Overcomes Ji Earth—Attraction and Challenge

The other side of mutual spouse stars is the Yi Wood overcomes Ji Earth relationship between the Day Masters. The algorithm lists this as the only weakness in the chart—but it must be understood correctly.

This 'overcoming' is not a synonym for bad luck. For Lee Bo-young, the Wood that overcomes her is her husband star; a husband is supposed to be the one who 'can manage and bear responsibility.' For Ji Sung, the Earth he overcomes is his wife star; a wife is the one he should protect and nurture. So this Yi-Ji overcoming is essentially the line of marital bond—it brings some tension that requires mutual adjustment, and it is exactly what both care about most and will never let go. The medium grade means this: the foundation is strongly attractive, but the relationship requires conscious effort, not effortless smoothness.

Both have the same Day Branch Mao, meaning their spouse palaces sit on the same character—what you value, I also value; at the core marital palace, they share the same frequency.

Year and Month: All Generating and Hidden Combinations—Alignment Inside and Out

Looking further at the Heavenly Stems and Earthly Branches, aside from the Day Pillar overcoming, everything else is generating and hidden combinations:

• Year Stem Ding-Wu generating: Ji Sung's Year Stem Ding Fire generates Lee Bo-young's Year Stem Wu Earth—the outermost aura level mutually nourishes.
• Year Branch Si-Wu half Fire combination: Ji Sung's Year Branch Si and Lee Bo-young's Year Branch Wu form a half Fire combination—energy at the foundation is aligned.
• Month Stem Ren-Yi generating: Ji Sung's Month Stem Ren Water generates Lee Bo-young's Month Stem Yi Wood—the level of action and interaction flows smoothly.
• Month Branch Yin-Chou hidden combination: Ji Sung's Month Branch Yin and Lee Bo-young's Month Branch Chou form a hidden combination—an invisible yet quietly connecting bond.

The Year Pillar governs foundation and external relations; the Month Pillar governs interaction and family. From Heavenly Stems to Earthly Branches, these two pillars are almost entirely in generating and hidden combinations, with only the Day Pillar overcoming—and that overcoming is precisely the marital bond itself. In other words, the structure of this couple is 'outer circle all smooth, core line requiring effort,' which perfectly matches the real-life image of a low-key, grounded, and well-managed marriage.

Timing Confirmation: Quiet Marriage, Two Children, Zero Scandal

Structure alone is not enough; we must see if reality matches.

Ji Sung and Lee Bo-young met through a drama, quietly married in 2017, and have one son and one daughter. They are a rare 'zero-scandal' couple in the Korean entertainment industry—for years, almost no relationship turmoil or negative rumors, often cited as a model of 'balancing career and family.'

This stability is the portrait of their chart: mutual spouse stars lock them together, Year and Month generating and hidden combinations provide smooth interaction, and the Day Pillar overcoming—both a challenge and the string that keeps them focused on each other. The 'medium' grade from the BaZi algorithm does not mean the relationship is bland; it means the foundation is strongly attractive but requires both to manage it with care—and they have clearly handled this task well.
