I totally wanted Teresse to end up with her knight Jade. Especially since, they're so cute together, he's also very reliable, and she really wants to be a court lady!
I've had a thought that the consort could've been Clarise (cause I would've loved some tsunderey like Endo and Kobayashi's... I forgot the complete title ) but she hasn't had much exposure. I do love me my Villainess wins the Lead's affection (人*´∀`)。*゚+
On the other hand, Rina hasn't had much screen time, so it seems like the late one just swooped in for the win. I think it was hinted before when the prince called Rina "wise" the same comment he mentioned during that past memory... not really much to go with till Teresse's realization... so it's kind of awkward?
also, the prince hasn't done much in terms of romance? so I can't really imagine him actually getting the girl, whoever his real FL is. Also, it just feels like he became hung over the girl because the ring chose her...
also, that was the only interaction they had before and just a few more when she became Teresse's attendant. so yeah this ship's iffy. unless it's the soulmate trope? maybe
