Q: Did Takumi have a crush on Lara?
I am going to be totally honest with you:
You have to remember I wrote this book a long time ago. I remember there being a moment near the end of the story when Takumi and Lara are holding hands, but it’s possible that 1. I wrote it and then later cut it, or that 2. I never wrote it but imagined it or that 3. I neither wrote nor imagined it but saw it in the movie script and liked it, or 4. that I read it in some fan fiction. Anyway, I can’t even tell you guys if it’s canon because I don’t remember. But it’s not canon just because I mentioned it in this answer. The text of the novel is the only source material for the novel! BBTTR! etc.
