First and foremost is the fact that he pleasured himself to the thought of Taku, which is clearly weird considering that Mitsu was already in high school by the time he practiced onanism on himself because of Taku, and uhm, I get that it was an act of 'love' or whatever (from my understanding), but it still doesn't excuse his attempt of commiting inappropriate deeds to himself especially to an ELEMENTARY schooler... But regardless of his unpleasant doings, I felt sympathy for Mitsuru when his backstory was introduced, I guess he fell in love with Taku earlier on because he received lack of love and affection from everyone, including his parents during his childhood, which led to him falling in love with a child who showed him affection in a friendly friend way (I know Taku was also in love in like a confused love way, but that's beside the point), since Mitsu never experienced things as such.
Anyway enough yapping, I rate this a 7/10 because the overall story was good and it had a decent plot (excluding the Mitsu gooning thing lalalalala)
