Nanami and I have been dating for three years. Nanami is beautiful, kind, has great style, and to be honest, she's quite popular. Such Nanami accepted my boring marriage proposal. I couldn't be happier. ...I was happy...that's it! By the way, with him! I can't believe something like that happened... Where does cheating start? I often hear things like this, but although each person is different, things don't really change that much.
