Its a manga where the male and female lead characters have to hold hands and stay near eachother and they have to travel somewhere,they dislike eachither in the beginning
Holding hands? Not only is it an incredibly lewd act, but it is also against the rules of social distancing. By promoting "hand holding", you are spreading corona and corrupting our youth. You should be ashamed of yourself. (Also, that manga seems interesting. I think I'll read it while staying as far away as possible from the nearest human being)
i kinda remember that manga if i'm not mistaken it's called "double arts" and only the female would die if they let go
I heard of an anime called Handshakers with such a premise, not sure if that's related to what you're looking for because it was more like a battle thing? It's supposed to be pretty bad, on top of having garbage animation.
