Beautiful art and sexy sex positions, and the small cute short uke.
It actually unexpectedly interesting because at first I was just came for the uke, but then it really has rich plot, a plot that really got me into it, not just keep having hot sex but no further development. I like the pace of it, having once sex scene 3-4chapters(I know it's gonna focus on the plot later it even better). I think the main thing I think this manhwa impressed me was that the story plot goes on naturally without getting disturbed by the sex,whether the flashback, or the trivial daily interactions in the plot was great, smooth and interesting.
Some says the uke looks like a kid, but I don't think the author makes his actions as a kid, I actually love the uke's personality so much, and it reminds me of hyesung in love is an illusion. And the threesome I actually mentally prepare when I saw the people's comments, it didn't bother me that much as both the semes were pissed instead of not bother by it at all.
