Where is the best place to put a flashback in a story? menulis it in a separate chapter atau blending it within the chapter?

In between the story! Example: anda could be talking about how sad it is to spend your anniversary alone, and then jump to how anda remember spending your first anniversary with your boyfriend before he passed away from cancer. It's just my opinion but I hope it helped! :D

in between the chapter

In between the chapter. Finish a paragraph where the scenario will cause the character to have a flash back. Go t a different page as if starting a new chapter and set the flashback in motion. Then on the selanjutnya page, continue your chapter in a new paragraph.
