You're twist my words and say I'm ignorant, even though I said, "I'm not saying that's impossible for Kasumi to have romantic feelings for Sakurako, but it could also be platonic." Who can not accept that it may be possible that she has platonic feelings for Sakurako !? You and not me!
And no, there does not have to be a sexual act, but I just do not feel like Kasumi is in love with Sakurako!
But I understand now, your opinions are facts for you, just like the kiss on the CHEEK.
