I always have this kind of nostalgia after finishing the last chapter from each of dr koto volume.
the kind of nostalgia like when reaching the end of a good slice of life series.
that "ahh that was good ride, too bad it's ended..."
@sarshi The series started in 2000, running in Weekly Young Sunday until the magazine ended in 2008; it was moved to Big Comic Original, which is semi-monthly, until it finished; the final tank printed in Japan in mid-2010. Safe to say it was successful considering it got a live action drama adaptation that ran for 3 years. So yeah a series was around for a while and thus has a lot of chapters.
