Very subtle or at least people are not talking about it, but when Sensei ask Aizawa how she was doing in college, she starts to tremble, maybe she is not going to college at the moment, and had to lie in order to keep the conversation from derailing
For Takayanagi there was inherent value on keeping Ogura on life support, he has someone to confide with, even without response he still has a father figure to speak his worries to, and share a learning experience with, which is something Ogure said he still was striving to, far from being a curse, it was an answer to the question of "what would the patient have wished to do"
Takayanagi didn't left the room because he didn't want to cry in front of Ogura sensei, he left because he wanted to flee from the confrontation of the daughter suddenly confessing her feelings to him, pages 16 and 17 depict him showing utter fear, while the daughter is panicking out of stress and desperation, Takayanagi is having a visceral reaction out of feeling threatened, he has a very bad history of dealing with women ending infatuated with him, without never really knowing him and then becoming disillusioned with him all on their own, it happened with a lot of his female students, with his ex wife, and now with the daughter of his father figure which makes the situation all the more awkward
As a philosopher and ethics professor, of course Takayanagi doesn't blames nor judges the decisions taken by Ogura's family, he is well aware of all the social, economic, psychological, and physical circumstances that lead to such an outcome
But that doesn't means he is willing to engage with having to deal with the daugther of his mentor telling him that she is in love with him, moments after learning that they have choosen to euthanize his father figure
