I was worried about that when I went through his route, too. (I managed to get him by as MC's lover by August.) Despite having a full heart since June, I believe, I wasn't able to trigger his cut scenes until August. My advice is to focus on spending time with him during daytime. I think the day of the week matters more than the number of times you hang out with him since your heart is already full (i.e. if you missed hanging out with him on a Monday, try hanging out with him on that day the following week). Feel free to correct me if I'm wrong, though. Bottom line is: just keep hanging out with him during the day bc all that's missing is his cut scenes.
(Also, the audition for the wrestling anime doesn't really matter at this point: it only contributes to the heart meter. I didn't get that audition when I went through Toru's route too, but it didn't really matter in the end.)
