Teacher never thought he'd be giving a lesson on THAT subject, but he's not complaining.
Also, my early guesses about Guwon are
1) The throwing up has nothing to do with him being insincere with their intimacy, but it's a physical reaction bc of smth else going on with his body/mind. Blushing like that afterwards means he either lied about everything but still finds teach cute or that he said the truth and the other personality is also affected by the kiss, but in a more expressive/experienced (human, even) way.
2) I alr guessed that he had amnesia and (again, unless he lied abt it all) now I think part of it is having another personality that does remember the past, but no idea how&why the other is activated except that it happens at night instead of sleeping. The fact he slept through the night seemingly for the first time in this ep. maybe shows he let his guard down and the other personality didn't take over, but could it have repercussions for the town if he's not there to watch over at night with the memories/knowledge of the other personality?
3) I think he's a zombie that was experimented on and fused with a living person's consciousness so they could achieve immortality, hence the 2 personalities. But what's the purpose of the town then? To gather capable living humans so they can also be made immortal?
So many scenarios and Jinwoo is even more of an unknown, but I think he mostly had to make tough choices for his survival. Anyway, I'm just speculating and theorizing cause it's fun and the author is making one of the most interesting stories, I love them for that!
