Vinter was fine at first, but something happen and he crosses her bottom line and lied to her. True, he might've had a reason to do so, but it hurt Penelope and she didn't like the fact that he didn't trust her.
Also, major spoiler, he's the one behind the transmigration. After the original heroine ending route, everything went haywire. Vinter was the one who turned back time for Penelope everytime she dies because he hopes she would stop Yvonne. So Penelope died thousands and thousands of time in Hard Mode because of Vinter and it finally broke her soul into pieces (and a piece of if went to our MC in Korea, so mc IS the real Penelope). Yeah, the Penelope in the Otome Game had to die ruthlessly every single time and stuck in a cycle that she couldn't escape, surrounded by people she hates. The novel gets more and more depressing as it goes on.
Ekliss.... *sigh* let's not even talk about that traitor...
Crown prince is the best y'all.

Umm the original Vinter in the Normal Mode does not like Penelope, the Vinter in Hard Mode does eventually fall for her.
And the one who keeps bringing Penelope back from death is Vinter in Normal Mode. He did this because the world was kinda destroyed by heroine Yvonne. So he casted a spell for Penelope to be born again and again to stop Yvonne until she succeeds. ..... and that's how he broke her soul to pieces, because she couldn't handle it anymore.
