honestly your reasoning makes sense but ngl where things are going i feel like she's going to end up with the pink haired girl's brother. esp bc there was this one line that bc of his smile she ended up paying the price of being charmed by him or smth, i dont remember the specific wording. foreshadowing maybe???
Rykard didn't do her wrong too. He was her victim even, and Asta's brother was one of the people who agreed to punish her.
I do think that Lango felt like a little bro and Rykard felt like a best friend where they both can tease and help each other. And yeah, she's got the most chemistry with the prince, but even then it's pretty vague.

Tbh I don't want Hailey to end up w any of the potential ML's. At the end of the day, they all did some shit to Hailey and Hailey did shit back to them. No matter how much both parties change, It'd still feel weird seeing them be lovey dovey lol the only one I think it wouldn't be weird w is Lango js bcuz they have no bad history but I feel like he suits more of the "annoying little brother" more cuz their always bickering. But yeah I just hope it ends with friendship and not a weird ass relationship. I think it'll suit the best for our Hailey but what do you guys think?
