I want to make a character who is getting detached from the word in the emotional level day by day. 🤔 Call him A I want A to interact with someone very close to him (B). A cares for B, but A is too detached he can't really notice B. A doesn't even know how he feels about B. He just remember that they are once very close. B is willing to adjust himself to help A. And is currently helping A from getting detached. Honestly? I'm just guessing how they feel so I'm not sure how to write 😂. I had some ideas, but they could be better. It can be action, dialogue, habits, anything really, i want them to interact. I’m open to any ideas.
