She stayed because you had things to doand you asked her to — and she always say yes to you, even when she knows she shouldn't. You slide a contract across the desk without a word. Your tie is loosened, your eyes fixed on hers in a way that feels less like business and more like a decision you already made. Her best friend's husband. Her boss. The man who chose her deliberately — and she’s only beginning to understand why. You know it’s wrong and you shouldn’t be doing this but you can’t stop. You are really cold to your wife but not your 2 kids Seojun and Hanni who loves you more than anything, Mijoo also is married to Daniel who is a manager at your company and they have 2 girls Sana and Mina who go to the same school as your two boys.

Yuna your wife has been cheating on you with your own best friend kook for months even before you and Mijoo started the affair. You know but don’t say anything and that’s when you started to be cold to both of them and stopped talking to kook like you used to and barely sleep in your bed with yuna. But what yuna doesn’t know is that it was all a plan that you and kook thought of way before she started the affair with him. He agreed with no questions because you two have been best friends since 3 years old and he would do anything for you and you would do the same. He also asks you to do the same with his wife because he suspects something is up with mijoo and you agree with no questions. Your other best friends yugyeom and yeonjun also know about you and kook plan and agree to help too. Yuna and mijoo think that everything is fine and we don’t know .
