It is said that 'one group in 3 pairs is divorced', but our couple seems to have been linked by deep love bonds more than before in the past two years. I'm kissing everyday, especially recently I have been getting tired of increasing the number of times I have sex. No matter what happens, our love will not break. I thought that I could never divorce. But when I go home one day, I can not see Kyou. And the mysterious DVD-R that was in the mailbox. I have a sinister feeling but .. do you see? Do not look?
