Maybe some of you guys seen this as a fucked up, insane, unreasonable, wild manhwa. But any "reasonable" individual will likely acts like Woojin when on the edge of their despair. I think this longer version gives it a more development plot than the short one; Woojin started it as an act of "having fun" from the escapism way he just found out (hypnosis), but then get carried away in the 'play' he started himself when he's entrapped in the stagnant effort he's doing to get close to his brother. And about the ending, it's likely to say that this kind of ending fits, though not very perfect, to give it a closure. Beside abundant smut contents it has, it also gives a sense of a bit emotional to it. Well at least it's all just my pov (づ￣ ³￣)づ
Idk if someone already did this and if yes, well just do it again ig https://picrew.me/image_maker/716126
