Inner Thoughts
Things haven't been going well with my husband lately... I know it's my fault... but I still just can't say it... I don't want him to hate me, I don't want to trouble him... But if things stay like this...
Wait? A cruise trip? We won?
...Maybe if we're somewhere different than usual, I can say it. Yes... I'll tell him. He'll surely... accept me, right?

There are nothing but boring men here... Whenever they open their mouths, it's all boasting and superficial, sugary words... They stare at my body—do they think I don't notice? Sigh... why are these the only kinds of men who approach me... Oh? That person is... Fufu, I might actually look forward to this voyage a little bit...
