Sakura and her husband have been married for three years. She left the company to become a housewife with the blessings of all her colleagues. Her husband is always gentle, treats her well, a normal married life like everyone else. No more text messages on the phone, no more happy conversations with others. Now, Momo only revolves around housework, sitting at home waiting for her husband to come home from work. The only pleasure for her to overcome these boring days is the drama on TV. And Momo's boring daily scene has been covered with bright, happy colors by another man. That is her husband's department head, who is also her former department head. Once when they went out drinking together, her husband was too drunk, so the department head had to take him home. It had been a long time since they had seen each other, so the two sat down to talk. Momo shared about her boring life, the department head also gave his advice on married life. When Momo told him about watching dramas, the manager was surprised to find out that he also had that hobby. So the two shared emails with each other, often texting and chatting about their favorite dramas. And then what was to come happened, the two gradually developed feelings for each other. A pure but extremely wrong feeling. I want to touch you. That was the text message that started this perverse love affair.
