I mean in movie when shinobu go on mission with giyu she said ‘isn’t the moon lovely’ in japenise this means l love you and also in movie giyu didn’t express feelings towards Sanemi that means giyu is taken and sanemi likes kanae
Yes but does Giyuu like Shinobu back? I don’t hate in Shinogiyuu or Sanekana (cause I’m a multishipper) but I don’t consider those two to be canon because they aren’t confirmed. Such as, we don’t know if Kanae reciprocated his (Sanemi’s) feelings.
