More interesting than I thought it'd be. Seems like series with young boys and older women are getting more popular lately, like with Sunoharasou no Kanrinin-san and Danshi Koukousei wo Yashinaitai Onee-san no Hanashi.
Personally, I find these series with an overly doting older woman basically mothering a kid to be really funny for some reason. Just very ironic, especially when the boy keeps trying to do stuff to seem more manly and it backfires.
