I smell jealousy Good to know they're starting to realise the feelings they have for each other so bravo professor Btw chapter 45 broke me so i had to make a short edit about it for my youtube acc haha
Yeah, it really looks like professor is intentionally teasing Jinju to provoke reactions. There could be something what prof knows about Jinju from the past, and how to pull her strings.
Not being able to do what you always good at anymore , lose a friend that you think you can always count on ( also have a crush on )and get betrayed by them and then be hated by the whole class That was... sad
You can read the spin-off from other manga sites like vyvymanga.net
