I am a regular office employee in a multinational company, and with my position, it is very difficult to gain the affection of Moe Amatsuka, the colleague I secretly love, who has an ambiguous relationship with my boss. I have seen her and my boss in affectionate gestures in that private office many times, and one day, when my boss and that colleague were kissing, I caught them. To prevent the situation from getting out, she approached me and said I had to keep it a secret, but how could I keep a secret when the girl I secretly love is the mistress of my boss, who is already married? However, the condition she offered was too tempting: I could have sex with her, but I couldn't tell anyone about her ambiguous relationship with my boss. It was wonderful; I immediately accepted without hesitation. We might not be able to be together, but being lovers would be worth it...
