I'm absolutely in love with tranny and his savage attitude ヾ(❀╹◡╹)ノ~

dear chey (btw do I know you??your username sounds familiar) to clear this up I'm not using "slurs" at all. Instead of expressing or explaining themselves what exactly someone dislike or disagree with an opinion/statement and prefer insulting/trolling people on the internet bc they need that kind of attention..makes them exactly what they say in the first place. Do you want me just to accept that kind of bullshit...would that be ok with you?
however I didn't intend to write that long and a mean comment today..I wish all of you a happy year in advance

I wonder is this manga/manwha based on the old or new version of the novel...?

It is from novel.

As for me I loved it. What's he supposed to do? Raping his straight friend and waiting him to fall in love?? Like all other yaoi?? He had no clue about the emotions of his friend, so he ended up with any other guy. Why does this makes him slutty???

"slutty" is stupid. Grown ass, single adults can do whatever they want with whoever they want. It's nobody else's business what another person is doing with their body parts.
If the uke wants to sleep with a different guy every day of the week, so long as he's not running around spreading STIs or cheating, it's his life.

Somewhere in the midway of the story I lost it. Till volume 5 everything was fine and then it got boring. Now I'm giving it a second chance, don't disappoint me horimiya ┗( T﹏T )┛

It was first drawn (very poorly) as a webtoon by the author Hero. I read it in an interview, he started it when he felt bored as an hobby and published it on his own website. I think it was completed in 10chapters that's the original story. Later they started this manga version. If you feel curious about the webtoon, its this one:

PS. Sorry my English isn't the best so please ignore the mistakes ;)

Umm..soo when the authors feels sad about finishing the story, why not writing a sequel in future??

Its more, unless they're paid to do so(theres a writer and an artist) they cant make more of it as the company ended their pay rent cycle with this particular story.
Webtoons work alot differently than other media, in that it's more heavily monitored by content amount and type and it's also contracted work.
Holy cow..now this is my 4th time reading this webtoon..I just love everything about..the storytelling, a badass uke, the art..dynamic ankles..aww I want to have a physical copy of it so bad :3
