They are so cute together, I love them. Waiting for the next chapter is gonna be torture!
At least Hajime was willing to say his feelings out loud now, even if he was interrupted, I'm happy to see it. If Rei spills the beans, will Hajime start believing Sainami was a boy too? I always wondered if he truly didn't believe Sainami after ch.1, or was just in denial about it.
Also, Rei even mentions how little Hajime's appearance actually changed, but she didn't recognise Sainami until now, does that mean her appearance changed much more?
