1. Being Your-Self.
Yes we all remember when Tadase first confessed to Amu, but was it really to her? He said he liked her "Would Be Self" and just hearing that makes me hurt. If someone said they like you in a different way would you go and change? Will Amu didn't, she just kept remembering that moment. Yet Ikuto notes to have a crush on her and over time it grows bigger and what we can call "Love"?? Which leads me to number 2...
2. What is Love?
Ok we also know that Amu likes/loves Tadase to say . But what is like? Does she just like the way he looks or how he acts? Because if you ask me to love someone means to love/like everything about them, not just one part ot personality. And just to say I think Ikuto is in love woth Amu. Unlike Tadase he fully accepts her personality and looks. When she feels down [[sometimes]] he's there to talk to her. Its like he's always watching over her. And if you have seen the Anime you may recall the episode where Amu and Iktuo are stuck under a tree together. Ikuto tells her she's changed. And before they got stuck the Chairman [[First President]] tells Amu that the people that have been watching over her can tell if she has changed.
3. Actions of Love.
Well, if you have caught up in the Manga and Anime you may notice how Amu is always falling down. And thus Ikuto is there to pick her up. When Amu loses food he's always replacing it for her. And the way they stare at each other in the eye is like True Love. But thats why in the latest episode in Shugo Chara Doki, Tadase notices how they show their love with actions. Desperately he copies it and holds Amu's hand. [[Hm..I think to Amu Tadase is just a pretty face.]]
