So in other’s eyes, they see her as the main lead???

I guess not. For me, she is really the main lead but she can't accept the fact or not aware of it.

in her friends eyes, shes the main lead. but to uer, its her bestfriend cuz usually in our novels female leads r usually Mary Sue and almost perfect. also i think she got the hints but wont accept it cuz shes risking her heart more in romance than in their friendship and she knew this is all temporary cuz its not her world
