I regret ignoring all seasons and series of Ossan's Love. I have never laughed this much watching a series. Episode 5 hot spring scenes was the most hilarious of all for me.
Some viewers will find some characters irritating. However, I find the writer a genius for meshing a hotpodge of characters together and making them work harmoniously, producing a very entertaining series. This has a little bit of everything and nothing excessive except for Chief's screaming and Haruta's reactions but I think they were necessary to complete the comedic aspect of the series.
I truly hope they do another sequel.

I enjoyed all Ossan's Love sequels but this is my most favorite one.

HIGHLY RECOMMENDED VIEWING
