Omg miss him too T.T

according to the really quick and easy google search that I did (100% would recomend. it's free too!)
unhinged
adjective
mentally unbalanced; deranged.
"the violent acts of unhinged minds". for manga context it's usually referred to crazy shit like jinx and killing stalking

I do google but I just don't understand how they use that word in sentence

Btw thanks for answering

Unhinged is basically a synonym for words like: crazy, insane, disturbed etc.

When someone says a character is "unhinged", in the context of a story, it usually (not all the time) means a character is so obsessed with another character (it can be because they hate them, or are deeply in love) that they will do extreme things that a normal person who has those same feelings would not do.

For example: If an "unhinged" character is in love with someone, they might do things like follow them home, steal their stuff, or take secret photos of them.

"Unhinged" can also be used to describe a character who does things that don't make sense, or are an overreaction.

For example: If a character talks to an unhinged character, they will think that the other character loves them, even if what the other character said was not romantic.

Oh! And an example of a commenter using it would be:

"Wow, all she did was help him pick up books he dropped and now he thinks they are dating! He's so unhinged and delusional!"

Now I get it. Tysm for all the explanations.(≧∀≦)

Happy to help!! <3
