I almost didn't read this manwha, because of all the comments but I got to say am glad I ignored the comments because I absolutely loved it. Love the characters especially Siwon(great character development), the rollercoaster ride, I liked that it was unpredictable and not just the typical story line. Well done author.
I really love the love between Heesoo and Dojun. Despite the pain Heesoo was in, he was willing to put it aside to comfort Dojun. Such a selfless love. I like the first couple too, but gosh the 2nd couple got me in the feels.
