The man in the car is a 29 year old called Choi Soo-Im, a direct subordinate of Min Cheol.
While both chatted in the car, Min Cheol briefly mentioned his marriage.
Mr. Choi almost caused an accident from how shocked he was.
“Who did you say, you got married to ?” said a random lady behind them. Apparently she was in the back sit all along.
News about his marriage spread across his department, they cheered and congratulated him.
Everyone was happy for him, except the lady that was also in the car.
In the midst of the chaos, the lady went behind Mr. Choi , gripped his shoulder and requested that they went somewhere to chat.
Apparently, Mr. Choi was supposed to give her updates about his personal life, whether he was dating or not, something of the sorts.
Mr. Choi initially told Miss. So Soo-yun that Mr. Cheol had no one he liked that way.
The lady, who is 33 years old and Cheol’s boss, asked with tears why he didn’t take notice of it.
Miss. So, who has been single all her life, already imagined marrying Mr. Cheol and decided on how many kids they’ll have.
After work, they both followed Mr. Cheol on his way back home, to confirm if he was truly married and also curious about what kind of woman his wife is.
As they waited, they saw Mr. Cheol approaching a woman, as though they were acquainted.
That was Ji ah, his wife, smoking at the dark alley and looking like a thug because of the padded jacket she wore.
Miss So looked very intimidated.
