with Jake, Sunghoon, Jungwon

Good

Heeseung keeps to the set order but switches over the moment a faster route shows up. Jake, who follows the procedure without flinching, accepts that shortcut as a result, and between these two the work moves a step forward without ever turning into an argument.

with Jay

OK

Heeseung answers with results instead of pushing back when an order comes in. Meeting Jay, who decides fast and acts immediately, the friction is frequent, but the logic lines up, so the work moves along without things boiling over.

ISTP × ENTJ

with NI-KI

OK

Heeseung takes the parts to bits while NI-KI designs the system. The beginning and the end unfold at the same table at once, so the work moves quickly, but neither brings up anything personal, and the people sitting nearby sometimes find that silence a little awkward.

ISTP × INTJ

with Sunoo

Disaster

Heeseung stays absorbed in their own thing, unfazed by whatever’s being said around them. Even as Sunoo talks excitedly for a while, Heeseung barely lifts their head, and Sunoo ends up drifting off to find another friend.
