Kana and I have been dating since college and are now living together with the intention of getting married. She's cute, kind, and has a great figure, and I would be incredibly happy if we could get married. But without my knowledge, she ended up with *him*, of all people! With my best friend, Nitta! I can't believe that something like that happened... I often hear people say, "Where does cheating begin?", but I thought that while it may differ from person to person, it's not all that different....
