I can't believe this —

How is this the season 3 finale chapter?!

My only solace is going back to the reddit spoiler post again and again and again, when I desperately need to see some progress ( T﹏T )

I'm just copy pasting from reddit. It is only a short summarised spoiler of the most important scenes from the last volume of the novel :

The last volume of the novel revolves around Baek's potential overseas transfer. But my favorite part is this: He visits Seo at his place, hands him a rash guard as a gift (they both made a promise to go surfing some time) and reveals he might have to leave soon. He tells Seo that whether he wants to be lovers or remain as coworkers is up to Seo and that he shouldn't worry about the confession. They part ways. Seo thinks to himself he should've chased after Baek and kissed him that instant but that "it isn't some kind of movie". However he starts to realize his feelings after remembering all of their time together + reading all of Baek's silly text messages and breaks down. As he rushes to the elevator, he runs into Baek, and cries. "The one who makes me cry over stupid messages...the one who makes me irrational. A shameless foe who ruins all my plans. I was mistaken. We are in a cheap movie. Meeting Baek Youngchan is the most wonderful thing I have ever experienced in my life. I had to admit it now. I like him just as much as I want to kill him" he thinks to himself, as he pleads with Baek not to leave, and confesses. They kiss and have what Seo describes as the "most passionate and intimate sex he's had". <3 The next few chapters revolve around their relationship and it's also quite long so I'll leave it at this for now.
