Okay, Eichi is aware that what he's doing is a bit creepy. But he's certain that this idol is the love of his life. Is it so wrong for him to chase what he wants?

It's always lined up perfectly. Eichi will go out to "look after" his object of attraction. And the stars always seem to align. Always, Eichi ends up in the same location as the person he wants to see the most.

If Eichi didn't know any better, he would start to think he's being followed. But that is just wishful thinking.
