1. Being Your-Self.
Yes we all remember when Tadase first confessed to Amu, but was it really to her? He 発言しました he liked her "Would Be Self" and just hearing that makes me hurt. If someone 発言しました they like あなた in a different way would あなた 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 または how he acts? Because if あなた ask me to 愛 someone means to love/like everything about them, not just one part ot personality. And just to say I think Ikuto is in 愛 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 あなた have seen the アニメ あなた may recall the episode where Amu and Iktuo are stuck under a 木, ツリー 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 あなた have caught up in the マンガ and アニメ あなた may notice how Amu is always falling down. And thus Ikuto is there to pick her up. When Amu loses 食 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 表示する their 愛 with actions. Desperately he copies it and holds Amu's hand. [[Hm..I think to Amu Tadase is just a pretty face.]]
