Hey I actually like this! ヾ(☆▽☆)
The parents, or in this case, the dad, might not be people you'd like irl, but so far they sure are good characters that I love reading about. Compared to so many other wishy-washy parents that two-dimensionally supports mc in every era-defying actions that they take, making the story seem so easy, self-indulgent and a bit boring, this is much more realistic/interesting and allow us a deeper view into how this society works and the views of that time, which is a good use of world-building through show not tell! Everytime these parents appear, they come with their own opinions, thoughts and actions nurtured by their own upbringing, giving them depth as characters as well as creating intriguing stakes and conflict with the constrasting mindsets of Cain that just all but begs food for thought, and I love it.
And also the fact that they haven't become annoying pig-headed obstacles yet, so I'm still rooting for their appearances because them being there would actually help Cain grow and develop as a character himself (๑•ㅂ•)و✧ It would be much more satisfying to see Cain actually being able to convince them, who are originally people with completely different beliefs, to his side, no?
