Dude she's so YN coded. She has no personality, no aspirations, and she's plain. Her whole life revolves around Eddy. She just waits around for him to turn up. Everyone else is so much more interesting than her and beautiful. If the premise of this manga was The Life of an NPC Turned Heroine then I think I would give the FL some slack for being as boring and lackluster in comparison to the ML. This doesn't mean I think Eddy is better than her.
Please tell me the four of them end up in a polyamorous relationship together! Please! I need it!
