So I read this spoiler from most likely another comment or from the forums.
Basically the baby is not the ML's baby. The father was the former crown prince. Currently the crown princess is already pregnant (hence why her father is anxious for ML and crown princess to get married/engaged asap). So even if ML and FL ends up together, the baby will still be born.

Rereading it after so many years made me realize that FL's so kind and understanding.
Whether it be when she was younger and waited patiently for ML to explain the reason behind gifting her the whiskers or whether it be now, when she's grown up and respected ML's choice of not showing his face by not looking at it even when she had the chance to (when ML protected and saved her from that crazy guy, ML's paperbag fell out and he even fainted. If she wanted to, if she had let curiosity win over then she could have peeked at ML's face. Yet she didn't. The first time she saw it was accidentally as it was right in front of her (when his identity is revealed))
I'm a huge Ina Simp. Like HUGE. The prettiest character, the beauty icon is INA! AND I DONT ACCEPT OTHER ARGUMENTS! Yura is pretty too, specially her body in her adult self (damn this feels weird to say), but Ina has a better face card! Ohh Organ, Perion, Yoohyun and Siwoon are also really pretty! Tbh Organ has a "prettier" face than Yura (Yura's cooler).
Also weirdly I don't HATE the shipping between Yura and Organ, Yoohyun and Siwoon. I mean yeah it's weird as fuck, not only were they both fucking children but technically Organ and Siwoon is their granduncles. But then again the devils always inbred between each species and that's the setting so ┑( ̄Д  ̄)┍ Also grown Yura and Organ look pretty good together. And I just love Yoohyun and Siwoon so yeah. My fav males ending up together is not something to dislike (even if very vaguely cannon).
Also you can see how big of a Ina simp I am by now. My fav male characters? Yoohyun (her son who looks like her) and Siwoon (Love-Hate relationship with him at first (with hate winning cuz he was a villain). Fell in love with him after he became a part of the gang, and Ina's simp (kinda)).
