Tangent: when looking up Mamoru Oshii I found an interview where he compared the work culture at Studio Ghibli to a communist dictatorship (“communism is when capitalism”), because people of the 1960s “Anpo generation” (like Miyazaki) have “no morals” when they believe their cause is just…
My biggest question was what kind of love we are talking about here, to me it sounded more like platonic or one-sided romantic love rather than outright sexual, but it is just vibes talking here.
Sidenote: I find it weird how much weight is given to the verb “love” sometimes: it gets used very loosely when you say you love spaghetti or your family, but suddenly when you say it to a close friend everyone makes a big deal out of it. My aroace ahh is showing here lol
I didn’t look into the book, but what I can say is that 恋愛 ren’ai implies romantic love.
The book is apparently written by the same Mamoru “Studio Ghibli is like the Kremlin” Oshii, who is most well-known as the creater of Ghost in the Shell.
From that same interview I found, I didn’t get the impression however that he would just make shit up about him and try to ruin his career, he said it would be a loss if Miyazaki (and another Ghibli figure) stopped making films. The book itself, going by reviews, seems to be even-handed about his short experiences at Ghibli.
