I don't think the bond was broken. Sasabe was just enduring the shock and the nausea that's why Utou didn't go all the way. He was aware that Sasabe wasn't ok. As far as i remember removing the bond was possible in this omega universe but it hasn't happened for Sasabe yet. I guess it will be the last struggle these two will have before their ultimate reunion.
Ok, i've been reading this fluff ball for 2 days straight and i've fallen deeply in love. But there is oooone little thing that confused me. In chap. 96 LiHuan says that the little girl with him is his sister's daughter. As far as i remember LiHuan's family consists of three people: His dad, his mom and himself. There was never a talk about a sister and i remember his dad was talking about being only three people celebrating LiHuan's birthdays. Is this a mistranslation? Or maybe when he said "sister" he meant a relative, not a sibling?
Seme heard uke's problem.
He needed a reason to get closer to him.
He shaved his own pubic hair (as shown at the end).
He lied about not having pubic hair. When uke heard this he felt sympathy.
They kinda became comrades (who had similar problems) and it all led to seme's ultimate plan.
Uke fell for seme.
Now seme is the happiest and uke has no idea what kind of a freak he has fallen for.
The end.
Beautiful, seishun kinema in a nutshell.
I laughed at the end, what a clever seme indeed!!
