I really liked this. I played through a few times but keep getting one of 2 endings--I can't seem to get the others. I either get the "bittersweet" or "It's all cool!" I'll keep trying XD;
I did want to mention that I saw a few small errors in my play through. When James is quizzing MC about senpai, he says, "This once (one) is going to be a little tough." And also in the bittersweet ending, it says, "Not everything goes you (your) way."
Just thought I'd let you know ^u^
