And by "break" I mean an emotion breakdown. I'm tired of those stories like where the guy finds out the person he's in love with, loves him back and he's just like "Oh... well that's great, lets do it." And he shows very little surprise or any emotions for that matter.

All I want is for him to be overtaken by joy, sadness, shock -something; and actually shows it. It doesn't really matter what he's reacting to, but i'd like for the other character to witness it and react to it.

Of the ones that come to mind, Kichiku Megane. Uke goes catatonic in a session with the seme. Seme reacts... The expression in this manga are great.

Calling (Otsuki Miu) has a good part with this.

Sono Kuchibiru ni Yoru no Tsuyu - they both break down for various reasons. Quite a good story.

Thanks for the suggestions! Anymore?
