Together with my girlfriend, whom I've been dating since college, currently living together with marriage in mind. She's not only adorable but kind and has a great figure—I truly believed marrying her would be the greatest happiness in life. Little did I know, without my knowledge, something had already started between her and my best friend, Nitta. The word "cheating" is something we've all heard before—some might not consider certain things cheating, while others do. I thought the same, and so did she, or at least that's what I hoped.
