This gets better and better. Disclaimer, my OTP is Siwon x Kang Jinha in this. Also, spolers to come. ( ̄∇ ̄")
I did have a gut feeling that Donghyun liked Go Siwon a bit and maybe he was slightly jealous of Kang Jinha, but I almost shit myself when I saw this:

And I kind of crack & low-key ship it. *feels guilty and embarrassed* ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

This chapter is a blessing. A more serious talk between the two and he sees how serious she is and they hug! And he has potential feeling too! Which is great. Ah, and the atmosphere, manga gods, was just... (๑•ㅂ•)و✧
I sincerely hope this will lead to romance and them being together. Even if it will be slow and demand a timeskip of two years (or however long until she finishes high school). Because it CAN turn into a good romance even with that big age gap [[ ლ(´ڡ`ლ) which to me is even better]], I am sure it can.
Imagine her, after a few years of relationship, maybe by that time they'd get engaged or something (anything) and decide to have a baby so the first kid can have a sibling. But that's just imagination land in my head. ╮( ̄▽ ̄)╭

See? He doesn't love Bum. Sangwoo you bastard need to go to hell.... But kill the bitch first!
Honestly I would have let it go if he didn't sleep with her.
Don't bring logic into this, I know my argument has none. Just.. my feelings after this chapter don't make much sense.

We have been aware since in the middle of the series that Sangwoo uses sex to fish for his victims. I hope your feelings would get compensated when I say the sexual acts he performs to his victims means nothing to him, I holds no meaning to him. He has 0 % care for his murder victims, (rather unfortunate but that's how he is) compared to Bum who he perhaps atleast has around 20 % sympathy? Lmao idk. Anyway, as of Ch17, Sangwoo is planning something. Don't take the sex too seriously, unless we were given indication that it's significant to Sangwoo, (and we dont since we dont know his thoughts) the sex meant nothing because he performs it to get his murder victims.

Yeah, I mean I can handle him pushing Bum down the stairs and breaking his legs, cutting him with a can, killing, and storing corpses in his home but seeing him with a woman is what got to me. ;__;

Where CAN I FIND IT HAHHAGGSGSGG(╯°Д °)╯╧╧

Trying not to give you spoilers but I'll tell you what I was thinking after reading that chapter.
Sangwoo obviously had something planned. He's been planning it since he took Bum to the store and in chapter 17 it's just starting to come together. Sangwoo had shown that he doesn't get a whole lot of satisfaction out of sex alone so there's more to it than just having Jieun there for sex. He put Bum in that closet because he wanted Bum to see.
Here's the guess I had after reading 17 as for why, which may or may not happen. Bum showed he was jealous of Jieun's closeness to Sangwoo during the bj in the bathroom stall. Sangwoo could just be toying with Bum's feelings to make him mad or sad. We haven't seen Bum angry yet so that could have been what Sangwoo was trying to do.
Can't say much more without spoiling but if you want I can tell you what happens. I think spoilers ruin the fun of reading it though.
Ya hear that? That is the sound of all the hearts shattering (including my own).
She is gorgeous and she tries hard for him, but it is still sad that she never picked him up. Also, can you imagine what's going through Zheng Xi's head right now? (/TДT)/
