Sapphire Night : Well, it’s just… there’s something I have to tell you. And it isn’t easy for me to say this. But, just promise me that if you don’t like what I say, that we’ll still be friends.

Wallflower Blush : We’ll always be friends, Sapphire. Why would you think that?

Sapphire Night : Because that’s just it. You see, I don’t know how else to say this, but. Wallflower, I… closes her eyes have a crush on you! Wallflower looks stunned I knew this was a bad idea. Why’d I listen to Juniper? Ugh! Look, before you freak out, let me finish. I’ve had this crush ever since the day you said I mattered to you, when I turned into Inkpire Blotch. But I was took afraid to tell you because, I didn’t think you’d feel the same. And, obviously, don’t. I understand if you rather we just stay friends. But just know that I think you’re special, really cute when you blush, and that you matter to me. Even if I am stuck in the friendzone. looks away, downcasted
