Can't believe I read 160 chapters of My Kingdom / Silent War in less than a day only to get jebaited by that trash ending.
Moby Dick was good though, I'll keep following the weekly releases.
Anyways, point I wanted to make is that I wouldn't say any of the characters in this game are Carbon Copies from Yansae's work.
Like yeah, they might be an amalgamation of traits, but how much of that is just generic hentai tropes?
Like scientist girl appearance and personality make me think of Li-Na or that psycho from bitch Moby Dick, but the girlfriend character doesn't make me think of any character from those two manhwas. Like there's one scene where her face looks a bit like Song, the teacher, but that's mainly because of eye and hair colours.
I feel like I could just as easily think that the artstyle has similar traits to Ratatat's because of the colouring technique.
