I do like that the topic of asexuality was discussed in this story, but it seems that they are confusing asexuality with aromantic. Asexuality means a person who experiences little to no sexual attraction, but aromantic means a person who experiences little to no romantic attraction. From what was presented in the story, it seems that Woo Hyung struggled with reciprocating romantic love, not so much sexual attraction. He was capable of feeling sexual desire for specific people, but not feelings of love. This doesn't mean he couldn't be both aromantic AND asexual, but I just wanted to clarify.
Other than that, I LOVED THIS!! There are so many complex emotions expressed in this story. It felt so raw and real. 10/10 ヾ(❀╹◡╹)ノ~
As far as I know, he can get it up for anyone. But also, looking back on the story, it seems like he views sex as a form of punishment after the incident. Like, he doesn't seek it out for his own pleasure, but as a way to either attach people to him, thinking he doesn't deserve anything good in life, or he wants to help/pity the other person.
I fell in love with her manga and now I need MORE webtoons! Reading her works feel like I'm watching a really good movie. It's just so magical The chemistry between the characters and the way the art feels ALIVE, is why it feels like I'm watching a good movie. Ugh, another fantastic story to add to completed list. I just wish there was more
