It feels off when A calls O a child or a kid and then licks his finger in what should seems as a shmexy way...
The English translator for the novel used "baby" instead of "kid", so it felt more of a teasing nickname and didn't feel as strange when their relationship deepened...
Now I can't get rid of the thought that there might be an orgy around me and I have no clue about it ╮(￣▽￣)╭
The pacing seems to be too fast compared to the novel... I liked the novel though, so I'll finish the manhwa anyway
