Can you recommend me some winter/Christmas dramas?
It can be set in winter, with snow, cozy and hopeful plot/feeling... Anything that reminds you of winter or Christmas.

 AH :

You can try this list: Winter / Snow / Christmas

Thanks, I found it a little later after asking.

You can add "Skate into love". I am on the half of drama (reason why I am motivated to watch more winter dramas), there was episode or 2 with snow. ML was video calling FL and showing snow to her. But I think that there will be more winter scenes and drama is set in autumn/winter + almost all characters are training winter sports.

"Tree of Heaven" too, it is full of winter, Christmas and snow sets. There are really nice winter/snowy scenarios. But it is heavy and sad drama.

"My girl", "Delightful girl, Choon Hyang" and "Dalja's spring" are all set during winter and holidays. So they all have a lot of scenes with Christamas decorations, snow and such.

When the weather is fine
