I think it's pretty comparable with Ayane's love for Akira. Both equally unhealthy.
Although I wouldn't really consider any of Akira's relationship as "healthy". They're all pretty fucked up in their own ways.
It's definitely similar. I wouldn't put it at quite the same level though. Ayane seems more desperate to be loved at all. Noriko wants to be loved by him specifically. Hence Ayane wanting to be the only one he's with, while Noriko plans on sharing him and is even happy he fucked her sister.
Ayane's love also seems to come more so from being lonely, than Sensei himself. She's also presumably influenced by the thousand other Senseis that have come and gone, like the rest of the first floor. Ayane and Ami are more similar in my opinion, all things considered, tbh.
Noriko's love on the other hand is about as sacrificial as it can get. She not only seems to be supportive of Imani if she wants to get with Sensei, but literally has wished Ayane luck:
At the moment, she's even casually agreeing to sacrifice her happiness for Sensei.
Ironically though, I'd still consider Noriko's love "healthier".
