Manthika

It's been a while since I've found a webcomic where the characters' personalities carried the entire thing, but here we are.  The art is mediocre with poor shading and lack of attention to detail, the story is a cliche heroine villainess otome novel isekai deal- and yet.  

The main character is hilarious, intelligent, and competent.  Her interactions with the cool, collected, befuddled ML are to die for.  Her "white lotus b****" sister is hilarious to watch.  The brother is a perfect characterization of his archetype as the "one who gets his hands dirty in the darker side of things" and honestly?  I love it for their interactions more than anything else.  Hilarious. 

Edit 2023 for Season 2: without spoilers, I do want to say the quality dropped a bit for me as it continued and the sudden fixation on certain aspects of relations after an event made me drop the manhwa altogether but it probably won't be something that bothers the majority of readers.  Them talking about a specific something for several chapters in a row just killed it for me is all.
