I fail to see how their relationship is romantic. I dont think NK has any feelings for SH. He is still deeply hurt about his teacher. Either he is punishing himself for it, or he decided there was no point in trying to fight back anymore like he just gave up. Sad sad. I think if anything it is all one sided. SH does seem to feel a little something for NK, he just doesn't fully realize it. He might just think it is lust rather than love. Which is why he was confused by his annoyance at NK always talking about or thinking about Inhun.
He better not be lying when he said he like it cause if they not a couple by the end of it imma be mad
