Kind of got disappointed when I saw that it ended without including the story of a possible love between Dowan and Chamin (I didn't read the 41.5 chapter, as I started the webtoon because it was marked completed.) But now that I did read the note and saw the webtoon myself (it's called room to room by the way) I'm looking forward to it!
It was fun to read and even more exploring side for me towards the kinks side.
