Telling a new friend you were turned on by them is creepy. Crazy response. If she didn't like him a lot, that would have been a friendship ending comment.
The stupid thing is that Ryouta literally didnt catch on that Yuria is having a big crush on him. If it was me, I'll immediately catch this hot kitten and follow up on that maid outfit talk.
"Hey Yuria! Wassup! So.. You know, remember our talk abour that maid outfit? Bet you'll look real cute in it. Yeah, I really wanna see you wearing it. Can I come over to your house? ;3"
