Anon wants a fic where Norway loves Denmark VERY, VERY MUCH and oscillates between jealousy and unadulterated hatred whenever someone gets too friendly with him (even if it's someone who has no romantic interest in him whatsoever, like Tino and Berwald). Denmark can be either oblivious, seeing Norway as a BFF, or knowing and loving the other's attention. Outside parties (i.e. everyone who isn't Norway or Denmark) must be aware, at least to some degree, of Norway's Yandere-ness.

The setting and time is up to author!anon.

BONUS if:
- Norway sics his troll on anyone who tries to talk him out of pursuing Denmark
- fem!Denmark
- anon somehow manages to make the fic a tragicomedy
