Nope! I made a comment about this as well when I reread the manhwa
Felix doing that was soooo wrong and even Felix knew that. But reading the scenes genuinely made me so uncomfy because of the no consent to do it thing.
I would skim over them whenever I reread lol
I'm currently rereading again and I'm already prepared to skip those chapters
Because not to mention, my heart genuinely ached when Felix ended up getting Gio's condition and Gio felt horrible. He genuinely felt like he was the one who caused it to happen to Felix because of the treatment
Don't drop it though! I'm pretty sure it's just that part that's super uncomfy/toxic
Other than that there's the unnecessary "met as kids" troupe but that was introduced before then so

Am I the only one who’s really bothered by Felix going behind Gio’s back and making him go through a medical treatment without neither his consent nor knowledge?? And an experimental treatment at that. That’s incredibly fucked up by Felix and serious medical malpractice by Danny. And then Gio finds out about it but chooses to deliberately deceive Felix and act like he doesn’t know and that his condition isn’t improving. Oh hell no. How did this sweet relationship turn so toxic so quick?? I haven’t read the whole thing yet but I am so put off by this that I’m heavily considering dropping it. I know it’ll probably get worked out in the end but that is such a serious breach of trust, in so many ways, that I can’t imagine anything making it okay again.
