Posting to clear up some things, in case other comments confuse anyone.
First of all, I have not replaced Kendo with Arato, and Kendo still has plenty more content than Arato does. Currently I *am* focusing more on Arato because I intend to complete all of the content I had planned for his route before switching back to Kendo definitively.
Of course, I don't take an issue with people here not liking his content. I do what I want to do, and often times that means I won't be able to please everybody. If you're interested in Kendo content, it'll come back in a few weeks. But even if some people think the Arato content is excessive, I promised myself I wouldn't half-ass things in the game, even if reception for a type of content is low.
For example, I know the Rin storyline wasn't too popular compared to others, but I still gave it quite a bit of scenes across several months. I've had an issue with plenty of porn games in which storylines or routes feel incomplete, and that's an issue I don't want my game to have. I won't change course from this way of thinking unless there's a significant decline in supporters (currently, it's quite the opposite). I want to give all routes and side-stories I started their proper conclusion, without it feeling like I'm cutting things short.
And maybe, just maaaaaaaaaaybe I'm also starving people out of Kendo content so he's eagerly welcomed back and I don't have to read "ugh there's too much Kendo so boring" every week while I work on the final arc.
