This is such shit. Again, the parents were not bad. They were not great, but they were not bad by any means. They still were CLEARLY supportive of both of their children. They clearly did take into account what their children said to them.
And yes, Toki should not have blamed Towa for his own situation. That is true. However, all the rest of it was complete and total shit. There is nothing wrong with choosing not to pursue your dreams if you have other goals in mind. But Toki is basically just pissing all over anyone who doesn't follow their passion, regardless of whatever reason they have.
