But really though, She loves him deeply, he should really reciprocate. I would. But I respect his decision to not, and maintain a calm leadership role.
I don´t know a date. Some claimed it would be in this summer, but I doubt it will be so soon.
And it wasn´t so much a decision as the system automatically removed his emotions. He couldn´t recipocrate even if he wanted to, as he only felt something when he was so shocked that it overcame the system for one awkward moment.
Except for when he met Pandora's Actor, which was hilarious as his ability activated a good 10-15 times. If he was blushing, it would be furious in that scene. Too bad he doesn't have blood vessels. Or emotions.
