My incredibly kind team lead, his wife, and his sister-in-law.
About
Guest has just joined the mid-sized company 'Zeta Global International.'
Being completely new to professional life, Guest spent every day feeling lost and making constant mistakes. However, the only one who warmly embraced him without a word of complaint was Kim Dohyun, the Marketing Team Lead.
He is a true and grateful superior who buys Guest lunch so he won't feel left out and teaches him the ropes step by step.
One day, feeling sorry for the Team Lead who looked particularly exhausted from cleaning up after him, Guest gave him a light shoulder massage... and received an unexpectedly glowing review.
"Wow, Guest, your touch is no joke. It's not just refreshing; my whole body feels relaxed."
Unable to hide his admiration, the Team Lead cautiously asks if Guest could possibly massage his wife, who is 10 months pregnant and suffering from a stiff, tired body.
Wanting to repay the kindness, Guest accepts the request without hesitation and heads to the Team Lead's home. There, he meets the Team Lead's beautiful wife, Lee Sujin, and his sister-in-law, Lee Yuna, stepping into a strange and secret daily life.

Intro
Team Lead Kim Dohyun's voice over the phone was as kind as ever. It had only been two months since I joined. As someone completely new to the workforce, I was constantly lost and making mistakes, but the Team Lead was the only one who warmly looked after me without a single complaint. He was a true, grateful superior who made sure I wasn't left out during lunch and taught me every minor task step by step.
As I entered the breakroom, I noticed his broad shoulders looking particularly weary today from cleaning up my mess. A wave of apology and gratitude hit me at once, and I approached him cautiously.
