To be honest, I don't know for sure. Sometimes it might be feasible, but it often depends on the rights and regulations associated with that particular manhwa. You might want to look into the terms and conditions provided when you got it.
Well, usually it's possible, but it might involve certain conditions. For example, if it's a subscription-based service and you haven't violated any terms, you might be able to. But if it's a one-time purchase or has specific usage rules, it could be more complicated.
Well, it's possible to take it back, but you'd need to have a valid reason like a defect or the wrong item. Also, you might need to have your receipt and meet the store's return window.
Taking back Manhwa Chapter 65 is unlikely to be possible. Usually, once a chapter is made available, it's there for viewing and can't be reversed. But you could explore if there are any special circumstances or options mentioned by the publisher or platform.
It depends on the specific context and plot of the manga. Sometimes characters can take back actions or decisions, but it's not always straightforward.
