What BOYNEXTDOOR Sungho's 庚辰 day pillar says about his ideal partner — read from his birth chart, not from an interview.
In Korean astrology, Sungho's ideal partner bends where he does not. His 庚辰 day pillar — the part of a Saju chart that describes what someone is drawn to — is hard Metal on soft ground, and the first stem in that ground is 乙, the supple vine, which is both his proper partner star and the one stem his own day master combines with. He is drawn to someone gentle and perceptive who reads him without being told, and who is not trying to win.
Sungho's day pillar is raw Metal set down on wet, fertile earth. The Metal is him — hard surface, sensitive interior. The earth is what the Metal is drawn to, and the first thing growing in it is a vine.
Three of his four visible stems and branches are Metal: 庚 above the month, 庚 above the day, 申 under the month. It is a chart that reads tough and is not, and the pull toward being number one is the part of it that costs the most.
So he is not drawn to another rival. Someone equally hard, equally driven to the top, would turn the relationship into one more ranking, and he has enough of those.
He wants something supple. Someone soft-spoken and flexible, who reads a room and reads him, and who does not compete. The 乙 in his spouse palace is the one stem in the system that combines directly with 庚, so the pull toward that type is not a preference in his chart; it is a bond written into the position.
Sungho's 辰 holds 乙 Wood, 癸 Water, and 戊 Earth as the principal.
Against his 庚 day master those are 정재, 상관 and 편인. The 정재 is his partner star and it is 乙, the vine — supple, yielding, growing around whatever it meets. It also forms 乙庚합 with his day master, which is as direct a tie as a palace can hold.
The principal stem is 戊, which is 편인: the quiet, perceptive, slightly unconventional mind. A 편인 spouse palace describes a partner who understands without needing it explained. With 癸, the 상관, between them, the position reads as gentle, perceptive and expressive, and the gentleness governs.
Sungho was born on 4 September 2003, in the 申 month — early autumn, 庚 as the principal stem, the same Metal as his day master. Metal born in its own season is at its hardest, and his has two more 庚 standing above it.
《穷通宝鉴》 on 庚金 in this month asks for 丁 first, to forge the Metal, and 甲 second, to feed the fire. He has 丁 and 乙 hidden in his year branch 未, and 乙 again in his palace. The 甲 is absent, and the 丁 is one hidden stem doing all the forging.
Metal this hard with this little fire is a chart that stays armoured. The classics want it worked, not matched. A partner who bends is the one the Metal can be shaped against without either of them breaking, and that is why the vine in his palace is the whole reading.
Read from stem combination, branch harmony, clash and 원진. Why these four →
Both halves — 乙 and 庚 combine at the stem, 辰 and 酉 at the branch — and 乙 is the partner star already inside his palace. The clean answer.
丁 is the exact fire 《穷通宝鉴》 asks for first on an autumn 庚, and 酉 harmonises the branch. The one that works the Metal.
甲 is the second thing the classics ask for, and 子 makes half the 申子辰 frame with his branch. Structure rather than warmth.
戌 is the direct clash on 辰, and it dries out the one wet branch his hard Metal rests on.
Two dragons are 자형. The second one does not steady the first; it duplicates the pressure.
亥 sits in 원진 with 辰 — more water, but working against the palace rather than with it.
Riwoo carries the same 辰 spouse palace over an Earth day master, where the same three hidden stems point at a different partner star entirely. Riwoo's 戊辰 reading →
This is who Sungho's chart is drawn to. Your chart says who you end up with: the age gap, their looks, how they show affection, where their money comes from and the years you are most likely to marry. Read from your date and time of birth.
Sungho was born on 4 September 2003, giving him a 庚辰 day pillar and a 庚申 month. Idol birth times are not public, so this works from three pillars rather than four. How day pillars work, and how far this method goes →
Your day pillar comes from your birth date, not your birth month, which is why a star sign cannot give it to you. Free, and about a minute.
FIND MY DAY PILLARSomeone gentle, perceptive and flexible. His 庚辰 day pillar is hard Metal on soft ground, and the first stem in that ground is 乙, his 정재 partner star — the one stem that combines directly with his day master — next to 戊, the 편인 principal. A partner who reads him without being told and is not trying to win.
Another rival. Someone equally hard and equally driven to the top turns the relationship into one more ranking.
庚辰, from his birth date of 4 September 2003. In Saju the day pillar is the relationship indicator: the stem is the person and the branch is the spouse palace, 배우자궁.
乙酉 combines at both the stem and the branch and carries his partner star. 丁酉 brings the fire the classics ask for and 甲子 the fuel. 戌 clashes with his spouse palace, a second 辰 forms 자형, and 亥 is 원진.
His 辰 branch holds 乙 Wood, 癸 Water and 戊 Earth — 정재, 상관 and 편인 against his day master. The 정재 is his partner star and forms 乙庚합 with his own stem, which is why the pull is a bond rather than a preference. The 편인 is the principal, which is why the partner is perceptive.
