I wonder, is this going to be a series that ends after the six days are over, or will it keep those six days going somehow, or will there always be another added time crunch for some reason? Or will the series' title just become obsolete?
Not once did the mc get flustered or spaz out. Kudos to the author for that. That alone puts this above average as far as JP harems go. It helps that Kuu was so forward. Really wasn't expecting another sex scene so soon and with different girl at that.
While the baseline concept of skill / stat growth via sex isn't new, the concept of skills becoming "better" by having new skills added to the host is at least interesting.
Though if there isn't something in the histories that documented this happening in he past, it would make me question why Kuu brought it up as a possibility. She's framed as only speaking of things she has learned, and not unfounded speculation.
I got a few questions about Kuu....oh well, just fiction
Also, in this situation as ruler, i'd just bestow the hero a myraid of lvl ups.... you know how, slaves etc... 7 days is just not enough to do anything much
