Because their soul is so near,and their character is suit.A cool,self-contained man likes Shun need a sweet,sensitive,precise and heartself likes Alice to warm his heart.
well of course ^^ they both Lost their parents...though alice has a very kind granpa but shun has a very hard hearted and pushy grandpa, and only alice that could understand him lonely boy+lonely girl= love
Because they have things in common: 1. They are both orphans 2. They both have a grandfather to look after them 3. They are willing too help others at all costs...
Because outside they seems to be very different...Cool and sweet...Cold and warm...but in fact their hearts are very near and same!They always keep their feeling deeply inside,and don't tunjuk their sadness without it's nescessary.And their relationship is very special! (But we can't be sure about the couples in that anime.It is always upside down.If I have a chace I 'll ask the director,but 99,9/100 he just 'll answer:"Why do anda care?Shun is a lone wolf!My industry is just making Bakugan battle lebih interesting,and that's all.Don't forget that this is only a kid show,and Alice-Julie-Fabia who fits with him,I don't care?And why do we need to care?Shun is best when he's alone!I want him to be cool, alone and something like this,because when he has girlfriend,he'll less cool and so it will never happen!Shun'll not has a girlfriend!Or it's just my thought or...I don't know,but I think the girls is not the things for Shun.He doesn't need them.And that's all!So,don't ask me anymore about that topic,OK?"
