I think when the seme said "I shouldn't have given you money", he meant (although at first, he only wanna enjoy a fling with a cute person like the uke just for some fun) He ended up falling for the uke for real. He really regretted using the money as a pretense to have sex and get closer, because it seemed that eventually he couldn't win the uke's heart. For him, the way the uke wanted some distance as soon as they finished with their sex, it seemed like he only wanted to do it for the sake of money.
For the uke (and for myself at first), might think that the seme simply regretted having sex with him, that he's not good enough and that the sex with him just wasn't worth the money he has given him. (〜 ̄△ ̄)〜

No matter how you look at it, Kuro looks just like any ordinary crow, but sensei just somehow made him looks so cool (I wonder how...) that I'm falling in love with a 2-D crow for the first time in my life ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

Well, I can relate to that. I've got a few friends who are scared of chicken and birds. One of them told me that they got chased by a big hen when they were young. Birds can be scary at times really. I wanted to keep a pet peacock myself and then I heard that some one got injured badly by them before, kinda changed my mind instantly. ( ̄∇ ̄")

That's the vibe I've got from seeing them together...sex buddies ( wanted to confirm my hypothesis but I don't understand Chinese ╮( ̄▽ ̄)╭)
So, the great obstacle would be how the MCs will overcome their hatred that got so deep from the very first meeting. I don't think it will be easy and with all that long list of raw chapters, it's not completed yet. Korean manhwas are very good that making your heart aches for a long long time with the seemingly-forever drama.
Perhaps they got cut off in the magazine...but yeah, I miss volume 1 when the chapters were like twice as long as they are in Vol.2...This is a good manga really...
The chapter in vol. 2 is shorter because the author is sick she even push herself just so she can produce the 10 pages but people keep complaining ┑( ̄Д  ̄)┍
Sorry, I didn't know about that. I think publishers deal with this issue differently, I would ask them to provide less frequent submission instead of shorter ones on the regular basis. Give her a proper break if needed. But what do I know...Hope she gets better soon.
