That's cruel of him. Okay he didn't submit to marriage paper. That can be forgiven, but letting go of her and not even trying to chase after her. Not even trying to get her back. What is he thinking??!!
Lots of people think that when you love someone just seeing her/him happy is okay, but if you really love her/him you couldn't stand seeing her/him happy without you. You would try to make her happy, wouldn't let go like Maa-kun.
Sensei what are you thinking? She loves you and you her, so why?

He stepped back and threw his arms out.
"I'm always crazy around you Rose. Here, I'm going to write an impromptu poem for you."
He tipped his head back and shouted to the sky:
"Rose is in red
But never in blue
Sharp as a thorn
Fights like one too.” - Adrian; Shadow Kiss

The whole letting someone go because you love them and for no particular reason at all think that they'd be happier without you is overused and retarded and I'm just disappointed the author went there. Shit, this chapter just left a bad taste in my mouth. And Shouma being so pushy, utterly selfish and inconsiderate towards Fumino didn't help.

+1 with chome ! But, we all know they will get back together before the end 😛 It wouldn't be shojo if they are not.

Btw, I didn't know this was gonna be the last arc...kinda shock me when I saw it on the first page. Do you guys know how many more chapters there will be ?
