As for the chapter:
Hypocrisy at it's finest.
Takayanagi was clinging to his sensei, he already cut his ties to life when incurable cancer hit, his "warmth" was there because life support system alone, I know that first hand since my grandmother died that way and as soon as respiratory system cut off her body became colder, she was long gone.
Serina point of view is flawed obviously, she has no self control and indeed is immature, but he doesn't know she does want she do to earn as much money, to live on her own by doing what she can in time her "goods" are still for the taking by pedophiles.
It's a shame her issue wasn't resolved, most likely because of story got axed.
As for the story:
It was good until second half of 2nd school Takayanagi visited, the use of ethics class to fix student issues became useless and their matters were unresolved, especially with that killer instinct kid.
Shame that Aizawa "relationship" came to the end with her making a 180° at life but having a boyfriend in the end, but that was more of
transference love, tho' he felt something to her as seen after he rejected her feelings when she graduated.
Was hoping that Maria Yagi, the one being raped then tried to commit suicide by jumping from the school roof, would make an appearance as Takayanagi did promise her to take her to a mixer when she became nineteen... guess author forgot.
Overall, it was a good read, felt flat at 3/4 when Takayanagi sensei cancer was brought up and was more focused around euthanasia for far too long, without reasonable conclusion.
Also, we didn't get definite conclusion why Takayanagi marriage fell apart.
8/10
