Well, damn. Okay. I mean, I thought Main Character was an arrogant, entitled asshole too but whew! Coming from your sister is quite different.

First impression is strong dislike of the MC but also impressed by how he just bulldozes ahead. I don't have to like the MC to like the story though.

Already introduced an annoying red headed woman "idol". Ugh.

She'll, of course, probably be redeemed because some blah, blah, trauma, blah made her into a total bitch but MC will do blah to make her see the error of her ways and blah, blah, blah.

This is so irritating. I hope he has more interesting developement and plot devices coming up.

Oof, shit translation is making this difficult to follow. Too bad. I was enjoying how MC is just going full speed ahead with zero regards to collateral damage.

For instance is MC's sister is referred to as both "she" and "he". Often by the same character, in connecting speech bubbles. Also, is Yoon J who's competing in K-Singer Star a man or a woman? Or intersex? It doesn't help that they dress very androgynously. The translator keeps changing J's gender.

Make up your damn mind translator.
