The Conclusion from chap 24.
I've read the rough translate.
Well as we know from the last chapter that they're stuck on lift coz of powerdown. Then Shirotani-san got nervous and remember the time when he hiding on his father closet ant that makes him nausea and hard to breath.
Then Kurose trying to call the building technician and they said it will work again after 10 minutes. And Kurose start talking to shirotani because he is woried with his condition.
And then he said shirotani-san are you okay? Are you feel disgusting because you're with me in this place? And you said I'm disgusting. (something like that)
And I don't remember what they talking about but then Kurose says will you come to me while offering his hand to shirotani. After a while finally shirotani chose (kiss) kurose hand and they're hugging.
And on this scene shirotani think that Kurose know everything in his mind coz they're this close (the trauma and his fear from touching people).
So, from this chapter we know that he didn't want to be touched coz he think people will know what he's thinking and doing. (it's coz of his father).
Well, I hope you can understand my comment coz my english are terrible.

you are soooo right
in the lastest chapters I am always with tears in my eyes when I read this manga
the words shirotani uses to refer himself are very hurtful
I found chapter 24, but in japanese, well if somebody understands here- http://aomadara.tumblr.com/post/129064244761/for-those-who-dont-understand-chinese
