Genshiken chapter 121 ends with Madarame apparently about to announce his choice of partner from among the four members of the Mada harem. This storyline Who will Madarame end up with? has dominated the manga for over half of the run of Genshiken Nidaime, since 2012 at least, pushing aside other questions like Who is the next president? and Will Ogiue make it as a manga artist? In the original run of Genshiken an academic year used to last two or three volumes, but the year of Ogiue's presidency has taken up eleven volumes to date. The current club trip to Nikkō, with its Mada harem kujibiki, has been going on since chapter 107 (first published in December 2014) or over two volumes. That storyline has been drawn out like a bowstring.
If I were writing this story, I'd release the arrow now. I think chapter 122 will begin several months into the next academic year. Someone else will be president, summer Comifes will be coming up or have already passed, there will be one or two new members, some of the old ones will be gone, and Madarame's announcement will already be club history. Part of what will keep the readers' involved will be the fascination of piecing together what happened, and I'm sure Kio will employ his powers of deferral to spin that out, ut there will also be the fascination of time advancing, which has been absent for a while.
I'll be proved wrong March 25th.
