While I'm not in any particular financial distress, I do want a bit more spending money.

Increasing my income is impossible, as part-time jobs are forbidden by school rules.

Therefore, I have no choice but to reduce my expenses.

My next-door neighbor is in a similar boat, not struggling financially but also wanting more money for recreation.

And so, my neighbor and I started a modest frugal lifestyle.

For example, to save on air conditioning costs, we might spend time in the same room, or try cooking together, something we never did before. It's a story about how our relationship gradually grows closer as we do various things, one thing leading to another.
