행복회로 (haengbokhoero) — wishful thinking that makes you happy.

Lesson 18 in our Korean Slang series, adapted from Korean Your Teacher Doesn’t Teach You by Injin Hwang.
What 행복회로 means
회로 means circuit. 행복회로 돌리다 playfully pictures a mental circuit producing happy predictions, often before any real evidence arrives. It can be self-aware rather than a firm claim.
A short conversation
A: 아직 면접 결과 안 나왔지?
B: 응, 벌써 합격한 상상으로 행복회로 돌리는 중이야.
A: The interview result is not out yet, right?
B: Right. I’m already happily imagining that I passed.
How to understand it
Start with the context in the dialogue. The speaker uses 행복회로 to mean “wishful thinking that makes you happy.” A word-for-word reading can miss the tone. Compare the Korean lines with the natural English translation, and notice which part of the situation makes the meaning clear.
Use it with care
Use it lightly about your own hopes. Do not dismiss someone’s serious plan or anxiety as mere 행복회로.
A more neutral or polite alternative:
좋은 결과가 나오기를 기대하고 있어요.
I hope for a good result.
Try it yourself
Has the speaker definitely passed the interview?
Show the answer
No. They are imagining a happy outcome.
Read the conversation aloud, then try the neutral alternative. Think about which one fits a friend and which one fits a polite conversation.
