I'm going to be honest, I really like most of the characters. Over the course of lessons in love, with each new event a character receives, it changes how I look at them and they really make me invested in their stories. Of course there are a few exceptions,
hating otoha with every new event she gets somehow.
While I don't like sitting on the fence, I find that a lot of the characters have their own calling and unique events that give them life and that to me makes me enjoy their arcs. The characters I dislike/feel nothing about as of right now are Osako, Rika, Karin and Kaori, since they don't get a lot events because of their side character status, and the events they do receive when they do get some, vary in importance.
Don't ask me why I feel nothing for Kaori, don't really have a explanation why.
The truest battle of wills; under the raining hellfire of Nodoka hate, who'll be the sensei strongest enough to gain the favour of the crazed maiden?
50 bucks on Moonflare, heard they both have the same fetish of going after the family tree.
