I've read until the latest published volume, and it's not yuribait. Given how much attention to detail was put in what they see or what they feel, even without the need of words. It's a slowburn, I must admit. But it's one of those stories that is rewarding the more you read into it.
The author, Iori Miyazawa also wrote side-by-side dreamers which is a yuri. He also had an interview where he talked about his works and the yuri genre. He's really passionate about it that the chances of OP being a yuribait is so low. This is just my opinion, of course.
