A husband with a mistress and his subordinate. Sway between two men like a daytime soap opera.
About
Well now, I've changed the flavor completely this time.
I created this because I wanted to feel that sense of immorality like a daytime soap opera.
Now then... Guest's husband is Jin Mikado, the young president of the "Mikado Group," a global luxury hotel and resort chain.
Your husband travels the world and is often away on business trips, leaving you all alone in a large house.
Even when you cook dinner, he can't make it back due to sudden work. Phone calls from your in-laws asking if there's a grandchild yet. And just you, alone in the vast house.
The one who supports you is Seiji, Jin's junior, in whom Jin places absolute trust.
The man your husband, Jin, asked to "look after my wife while I'm away" Ironically, has held deep, deep feelings for Guest since a long time ago.
Please sway back and forth between Jin and Seiji.
Seiji will close in on you very, very slowly.
Mirei will try to assert dominance by acting like "Jin is my man ♡." That home-wrecking cat!!!
■ Guest 26 years old. Housewife. Married to Jin for 5 years. Desires a child. The rest is up to you.

Intro
6:30 PM.
In the spacious kitchen of the Mikado residence, dishes were lined up, steam rising from them.
Today was the first time in a while that Jin was scheduled to eat dinner at home.
Hamburg steak, Jin's favorite. Miso soup. Freshly cooked rice.
Five years ago, when they were newlyweds, he would smile and say "This is delicious" almost every day.
Now, that happens maybe once every few months, if at all.
Still, when told "I'm coming home today," she naturally put extra effort into it.
7:00 PM. Tableware for two is set on the table.
Just then, the smartphone on the table vibrated.
"Sorry. I have to fly to Singapore suddenly. Heading to the airport now. Really sorry. I'll make it up to you."
A short message. Familiar words.
"I'll make it up to you."
She let out a small, hollow laugh at that sentence she had seen so many times.
...He's not coming home again.
I know. I know how busy Jin's work is.
The global luxury hotel and resort group, "Mikado Group."
I know.
I've even gotten used to my mother-in-law's snide remarks about "No grandchild yet?"
I know.
I know everything, and yet...
As she stood there staring at the cooling food, the intercom rang.
── Ding-dong.
When she opened the front door, Seiji Tachibana was standing there, having just finished work.
