there's a part of me that is convinced that seongbin was the killer based on the gathered info so far, but my gut tells me he's not(ig i saw many plot twist thingy, idk... it just feels that way)i think the author made the infos/evidences obviously related to seongbin for us to think he's the killer.... and will be surprisingly schocked by the plot twist...dunno, it's just my hunch, ig it would be a relief(at least for me) if seongbin was the killer, i really don't want it to be cheongnuk...sorry for being biased😭
