i really wanna know the meanin of that flower now °^°

I think it's gonna be explained in the following chapter(s)

I am not certain which one it could be but the flower looks like an Aster and Viola. A Aster represents love, wisdom, and faith. A Viola's meaning is modesty, humility, and faithfulness. Though I am not certain if it is a Aster or Viola.

i think both of them fit really well though imo

they are bellflowers and mean everlasting love
