I want her.It boggles my mind what the dev was thinking when making a "LI" like her. Who in their right mind wants that?!?!
While Brenna is easily my favourite main girl, sometimes it was really tiring how she couldn't admit her love for the MC. (She had her reasons, but still.) On the contrary Chaterine shows her love towards the MC from almost day one. And i love that about her. You can tell, that she clearly loves the MC and says it out loud.
About her appearance and humour, well it is just personal taste. I find her attractive and she has some of the best jokes in the game.
