It's going into winter where I live and I was wondering if anyone could recommend some BL series with a cosy vibe, please? I know that cosy is a little vague and can change from person to person, but if it felt cosy to you, I'm all ears. They don't have to be set in winter by the way! And I'm not looking for teen romances at the moment

(Off the top of my head, Old Fashion Cupcake and Boys Be Brave gave me that cosy feel I'm looking for)

Jack o' Frost has some excellent woolly jumpers :) It's a good series too.
Bokura no Shokutaku YES :) featuring the World's Cutest Kid and Most Adorable Wingman
Kinou Nani Tabeta? Romance within a relationship between men in their 40s
