The ending dance sequence was just perfect and satisfying. Though I'd like to see the characters find out about about Ren's gender. This manga was so clever with all its classical composer references (even though I didn't understand most of them until I looked it up). I also really liked the author's character designs where all the characters are easily distinguishable (I think that when there are so many male characters a lot of authors have trouble making each one look different). I'm going to go check out this author's other work now. Will miss this one!

In chapt 17, Sangwoo says "since it's our anniversary, it's pointless if you, the main character is not there."
So he's been trapped at his house for a year already?!?! For all the things this manhwa does well, the sense of time progression is confusing.

If you remember, there's that one chapter where there seems to be a time lapse of some sort. ┗( T﹏T )┛

I think the biggest time marker (if not the only marker) are his legs. He only needs to use a single crutch and can therefore place most of his weight on his legs for an undetermined amount of time (we'll go ahead and say an extended period).
I got a bit more into this than I meant to? I know ya'll didn't ask for it, but I'll throw it out there for jabs, anyway!
A medically treated -minor- (or stress) fracture to a leg can take six to eight weeks to completely abandon use of crutches and/or a wheelchair, but Bum not only didn't receive any medical attention for his injuries, but he also suffers from malnourishment (which can notably slow the healing process), and those breaks were anything but minor.
What we don't know is if both the major bones in his legs were broken (the tibia & fibula), or if it was just the tibia (shinbone). The second factor is the type of fracture; personally, I have a hard time believing he suffered anything less severe than a comminuted fracture (where the bone breaks into multiple pieces) given the circumstances (especially now that it's been a year and he's still using a crutch).
"Some tibial shaft fractures heal within 4 months, yet many may take 6 months or longer to heal. This is particularly true with open fractures and fractures in patients who are less healthy." That's 6 months or longer with medical treatment (insane)!
Poor Bum doesn't have the luxury of modern medicine (let alone a well nourished body that isn't under immense psychological stress 24/7) to help him recover, so we can pretty much double that recovery time and voila! 12 months have passed and Bum still needs a crutch.
Granted, we haven't had many opportunities to see him actually needing to use crutches, so before seeing him with only one crutch, it was probably a lot harder to tell if it'd been any longer than a few months.

I was about to suggest the same thing. Other than the blatant time lapses, the healing of Bum's leg is a pretty good indicator/estimate of the amount of time that has passed. I love the little context clues that Koogi drops in here and there for us (๑•ㅂ•)و✧
(This is quite unrelated but,)
I heard there was someone who asked Koogi in ask.fm (?) about the way Bum holds his spoon (not quite sure about the details since it's in Korean), Koogi responded and expressed that she was glad someone noticed! Hahaha gosh I love Koogi. <3

Another thing to consider is that Bum only really walked on his legs when they went out together, and that was not very often. When he was at Sangwoo's house, he was mainly sitting and crawling around, slowing the healing process even more. Leg injuries heal faster when you gradually start using them again and exercising, not just sitting around all the time. This did not help Bum's injuries either, making his legs heal even slower.

i think the author really put some effort into this manhwa. if you notice sangwoo's house, everything in his house is so consistent. plus all those little clues that lead us to what we have now. you should try appreciating the hidden genius of it

This author can sure weave together a story! Honestly, I often don't find many yaoi plots very satisfying but this one's good.
I did think it was weird that anyone would even SUSPECT of a romantic relationship between cousins. But that's yaoi for ya.

Yeah, I like how the story ended. Although in some cultures marriage between cousins is okay, I still don't think that it is healthy. I was about to flip tables if the main character left senpai . . . no one leaves senpai once you are noticed . . . that is the code of "Notice-me-Senpai" Once unnoticed, you can never go back . . . ╮( ̄▽ ̄)╭

I enjoy these more plot heavy stories. There is a Romeo and Juliet quality to this manga.
I like the part where Asahi got to keep something important to him from what he was running away from. I think that's a good message. I'm not sure how I wanted it to end, but endings where the characters run away from everyone else don't really feel satisfying to me.
"My conscience feels like it's starting to grow fur."
Is that a common Korean idiom or something?
it most likely means that their conscious instead of being "smooth, straight, clear to understand" it's now "fluffy, blurring the lines, not right"
