About the room
A small company, a long table, and charts that stay on paper.
The official registered business name is Percept Trellis Co., Ltd.. The business was established in 2014 in Suwon.
The first year was a set of evening circles near Paldalmun Gate. Han Sora rented a room above a stationery shop and invited people who wanted to mark horizontal levels without a ticker running in the corner. Attendance was uneven. The method was already the one used now: a line needs a reason, confluence needs independent reasons, and a scenario needs a sentence that can end it.
In 2019 the company moved to the present study at 105 Paldal-ro, Paldal-gu, Suwon-si, Gyeonggi-do, 16253. The velvet and the dark wood came with the room; the work stayed ordinary and specific. Park Minjae joined in 2021 and took the Saturday Level Notebook and most of the Open Chart Hours. Han still keeps the Confluence Desk.
How a sitting is run
Clients bring one instrument they already follow. Instruction is in English. The tutor will not log into a brokerage account, will not size a position, and will not stay on a messaging app after the hour to call entries. The commercial offer is the sitting itself: time, a desk, a printed chart if you sent it ahead, and a map you can carry out.
Paper is deliberate. A screen refreshes and invites another indicator. A print stays still long enough for an erasure to matter. Clients who want a live feed can watch it before they arrive and after they leave.
The people in the room
Han Sora has taught level marking here since the 2014 circles. She is strict about wick-only lines and relaxed about silence while you write. Park Minjae keeps the group morning orderly: six seats, one closed chart, sentences copied as they were spoken.
The notes on this site are teaching pages from the same craft as the desk. If you want the hour, write to the room and name the chart you will bring.
