I and Kana were dating each other, but she ended up marrying another girl. However, she never left me, and we still occasionally have secret affairs. But since my business trip about a year ago, I haven't seen her again. This time my business trip is to Tokyo, where Kana lives. When I called to say I wanted to meet Kana, she came immediately. We rushed into each other, not wasting a single moment. Kana is still the same, beautiful and charming. But there is always a look of sadness on her face. When talking about our affair, Kana couldn't hold back her tears. I know I have hurt her, but now I can't do anything. The only thing I can do is make use of this short time, trying to make her feel warm, happy, something that I may never be able to give her again...
