So for those who was rooting for other male leads aside from the crown prince, here's the reason why Penelope made the right decision of choosing him in the end.

Penelope didn't choose Eclise not just because he betrayed her in the end, but on the early stages (which was a bit hinted on most of the recent chapters now), she actually noticed that Eclise' favorability meter is rising too quickly and it made her concerned cause she's in the "hard" mode of the game and she knew that something is wrong with how easy she could make his favorability meter rise. Later on, it will become more concerning for her when the color of Eclise' favorability meter changes from red to a more darker shade of almost purple and since red is similar to like love, the color red becoming more darker for her is dangerous. And besides, Eclise is the one who would bring Yvonne back to the mansion so, nope.

Reynold is totally out of the list since she would actually consider him like an annoying but caring brother later on.

Derrick is a very lost cause. Right at the very end of this hunt, Penelope would be accused of trying to assassinate the Crown Prince and this bastard would only speak of how everything Penelope does tarnishes the reputation of their family. Hell, both the Duke and Reynold knows that Penelope didn't do anything wrong but Derrick tries to persuade her to plead guilty to the accusation of assassinating the Crown Prince just so she could get off with a "lighter" punishment (or in other words, so she could not drag the reputation of their family down anymore)

Vinter is good. He genuinely fell in love with Penelope but his realization was a little too late since Penelope was more inclined on the Crown Prince when he confessed to her. But it was also for the better since its his fault why Penelope dies again and again on every timeline Vinter resets.

So in the end, Callisto is the better choice. Sure, he is a bit too cautious, cruel and intimidating on the beginning. Penelope even rejected his first confession since she believes that he isn't still seeing her as his equal partner but he would eventually realize just how precious she is for him when she almost dies. And believe me, he would do anything just for her. So, Callisto the best boi.
