<continued>
Before starting the story arc, I'd just like to mention a few things.
Since leaving Shogo, Kanata has become an idol. However, she didn't tell anything to Shogo, and thus Shogo's a little PO'ed.
On a side note, Neo also auditioned for becoming a model, but she quit while Kanata stayed.
Spoiler:
<Neo True Endine Arc>
Kanata walks into Cubic Cafe, and proceeds to ask the owner on a date.
<insert stuff from anime>
At the hospital, Neo is reluctant to approach Shogo. (Due to her guilty conscience)
Shogo and Neo get along OK well, but their distance increased after the owner's death.
There is no longer a gathering spot for the gang, and Shogo's depression over the owner's death isn't helping either.
Meanwhile, Kanata has become increasingly clingy onto Shogo, and being the indecisive protaginist, Shogo doesn't know how to say no.
Neo, now a regular visitor of Shogo's appartment, knows about Kanata's visits, but doesn't say much.
Until:
<Insert Kanata's attempt to seduce Shogo>
Basically, Kanata leaves just before Neo arrives...
(Or worse if you chose the wrong decision)
But lying on Shogo's bed is Kanata's ribbon (You know the ribbon that she removed as Kanata undressed.)
Shogo finally admits that Kanata has been visiting, and promises to break off the relation immediately. (Procrastination = BAD ending)
However, Kanata secretly stuffs the ribbon back into Shogo's pocket. Shogo returns to Neo.
Eventually, Neo begins to 'invade' Shogo's appartment, as they become more steady.
But one day, Neo finds Kanata's ribbon...
When Shogo returns home, all Neo's belongings are gone, and the ribbon is lying on the floor.
<etc. etc.>
Finally, Shogo finds Neo, and makes up. Asking Kanata to the bridge, he returns the ribbon to her, stating he intends to make Kanata a memory.
Ribbon falls into the river, Kanata leaves for America, Shogo makes up with Neo.
