Hosik's story
I really enjoyed this webtoon! I know it seems wrong, but I honestly liked Sungyeon's character. He reminds me of Yoo Jung from Cheese in the Trap with the lighthearted kind of twisted personality going on (not like the usual hardcore messed up psycho twisted kind, if you get what I mean). Because of his innocent yet obviously wrong in every sense of the word actions that he makes, I couldn't bring myself to actually hate him (the same dilemma whenever it comes to Yoo Jung), and that's what I find just so interesting. And also, I looooved Jiwoon's character. He's such a great friend to Hosik, and their banters are always funny.

for the first story, i wished the mangaka didn't summarize the ending. it would've been nice to know what happened after "that" incident. for the second story, it's meant to be read for older readers due to the complexity of the plot. lot's of contradictions going on that had me scratching my head at times.
