Sometimes, Aichi just wants to tell Kai the thing.
It starts when he sits there at schools and his class is not really boring, but also not interesting enough to actually listen to the stuff their teacher talks about and he takes out his deck case carefully, hoping no one else sees him and takes out the card at the top of his deck.
Blaster Blade is a knight in shining armour, a knight who is afraid of nothing, someone who can do everything he wants without worrying or hesitating or being nervous and Aichi is not like Blaster Blade, but he wants to be like him.
When school's over, Aichi stuffs all of his things into his bag. On his way home, he walks through the park, hopes to see Kai laying on one of the benches, but does not and he gets a little disappointed, because, yeah, he really wanted to see Kai. At home, he eats and his confidence boosts up again and he really wants to tell Kai this thing now.
But he's got homework to do and the card shop is closed today anyway and Kai was not in the park, but there'll be tomorrow, right?
So Aichi starts thinking about what he'll say, what words to use, wonders when he should say it and how to find Kai somewhere alone, without the possibility of Miwa or anyone else interrupting them.
In the evening, he lays in his bed and he has every little thing played out in his head, has thought about every single possible scenario.
When he sees Kai on the next day, he doesn't actually tell Kai, simply convinces himself to do it tomorrow.
But tomorrow is not today and tomorrow never comes.
