Holy crap! Communication! Yay! I was expecting this to drag a few more chapters at least, but nope, they talked the very next chapter. He laid it all out there for her to hear. He was vulnerable. She heard his issue. And she is going to stay there and listen to him fully. Although, we already know she has a thing for him and wants to get to know him better so this works out.
i think, in this whole chapter, the most telling thing that she views Reiya differently than every other girl was her calling him “Tohno-senpai” rather than ”Rei-sama” like every other girl in the school. I’m actually surprised Youta didn’t pick up on that, but I guess with his emotions being all over the place it would make sense.
He should also have been noticing she was there waiting because she wanted to see him. If she were truly after his brother her mission would have been accomplished as she got close to him to talk and she would have ditched Youta…but she didn’t.
All in all great chapter with a lot of character growth from our MC while getting over his trauma that every girl is after his brother. You love to see it.
