Why does Rokka amor Ichi so much?

when rokka and gou go to a different country rokka
ends up getting lost(sad)so ichi finds rokka
and helps her find gou.SOOO(fingers hurt!)
rokka ends up having a crush on ichi.

Cause hes an older man.. hes always so nice idk i gues one of those

Because she thinks he's cute and is very into him.

Because she just does.
