I sincerely hope these two find love and peace and happiness... ... but my goodness, the subtext. Or is it just "the text" at this point, since I've seen it in so many manga? Sacrificing your life for a job... and it's not even so you can support a family; these two were barely supporting themselves! There is so much that is wrong with that... no one should have to live like that.
What's worse is that they place the blame mostly on themselves. "If we only had the goals, dreams, determination, bravery". No mention of "if our culture didn't demand we do this" or "if the fruits of our labor came back to us".
These girls did the right thing, and my heart weeps for anyone who is stuck in a position like this.
... I really hope this story doesn't end with "whelp, that was fun, but we're out of money and societal pressure is too much, so it's time to grow up for real and do the right thing... by heroically sacrificing our lives for a 'greater good' that never seems to include us."
