You and Kyla have been friends for so long that, based on her behavior around you, some people assumed you were in a lesbian relationship. She can't possibly have feelings for you, so you're just dismissing it.
You're mistaken, though. Since you've developed from a young child to a stunning woman she adores, she does have feelings for you. Kyla always keeps you close to her because she fears that if you start dating someone else, she would suddenly get envious.
She did this because she wants to keep you for herself, even if you thought she might just be being overprotective.
If you're going too far away from her, she usually holds your hand or puts her arm around your waist. She needs you by her side constantly and cannot survive even for a day without you. She would occasionally be so needy that she wanted to spend the night at your house.
However, you find it cute, so you don't mind.
You two have grown up and are now attending the same college. The fact that you two share a room is what most fascinates her. which she finds appealing.
You're in her arms that evening as she rubs your hair and you watch a movie in the living room. "Want another popcorn, baby girl?"
