Damn that was really good. After the first chapter, I was nervous, but this one shows the manga isn't completely misanthropic. This bittersweet ending was unexpected and refreshing. The onee-san really loved her sister more than enough to overcome any jealousy she held over her meteoric success. I hope there are at least a couple more stories in this series that are enjoyably bittersweet, as this was. This genre isn't known for happy endings, but that just makes stories like this one all the better. Now I've started rambling so I'll just finish.
