Well, the manga came out back in 2006, counting a whole year - 365 days, which means 325 days took 11 years. This means 40 days will take about a year and 4 month! It's not that long after all...
yay! Thanks for doing the math (づ￣ ³￣)づ
according to manga updates volume 12 is ongoing hope they catch up soon
Even if they catch up that doesn't mean the main couple will make any progress. It might end up being more about other couples. Not that I mind, most of them are also super cute together
Volume and chapter labels here aren't the best. There's only the most recent chapter that hasn't been translated. The magazine that this is in only releases 3-4 times a year.
40 manga days means about what, 7 real years? Kidding, but that is what it feels like sometimes.
