Bruh, she was never allowed to be emotional or express her emotions. Being with ML allowed her to open up more and I feel like she's allowed to have all these feelings with how she grew up.
Though I agree that alot of FLs are annoying.
This time the FL's personality and actions are justified. She learned to bottle up her feelings and never complain, "getting emotional (crying), avoiding and running away" from the cause of new discomfort or the emotion she feels is acceptable. Those emotions are new to her and she's not used to handling those ,but we see her growth and being comfortable and secure in herself and their relationship, which is also realistic.
Exactly
I really wanna enjoy this story coz I love cohabitation and age gap mangas but it's really hard . The FL is really annoyingly emotional,constantly running away and avoiding the ML. I dont know why every single shoujo manga has this type of character. Honestly, teenage girls arent like this ,yes we can be insecure and emotional but not to the level shoujo FL's are. It's really frustrating to read such characters and just ruins the experience,especially since it's such an overdone character troupe.
