I too agree it is not crush. She did not feel for him at first sight or is impressed bcoz he is handsome and ACP all. He is not even her Prince Charming yet but still she loves him the way he is. She has seen a lot with him his hatred, his anger, his sorrow, his happiness, endure his punishment, his love, his care oh my god I can go on and on but with all this she was with me, she is with him and will be always. The way she express or show can look childish but her feeling is pure. This love feeling for him grew gradually and strongly like we build a house. She does not want him to change she just accepts him the way he is although she wish he can be a little more expressive.
