i doubt Shell's father was in love with Ellie

I think Pain and Brutal had a thing. I don't think Pain was too into art except as art for art's sake (and a nanny). Ellie was into White (Brutal's daughter) and Shell just unknowingly told his dad the half-breed lives.
BTW, why do all the vampires have names like "Pain" and "Brutal" but not Shell? I mean, it's like he was doomed from birth.

I wonder if there will be any plot twists in this manga

Oh, i betcha there is. You know I read Ten Count until the chapter where they flashback Kurose's past. I realized that its gonna be a fucking twist in this or an excruciatingly sad ending. Even though Kurose is a psychologist, he himself has this mental illness that hadnt yet discovered in the manga. I dont know about other readers but its so obvious to me that i was like IM SO DONE OMG!!! And so i stopped reading this manga. I will wait until its all out so I dont have to IMAGINE what will happen to Shirotani @&$%#* (╯°Д °)╯╧╧

omfg please stop saying those things :( they are gradually getting their relationship better

Well, the thing is though, Shiro isnt the problem here, Kurose is. We can see that Shiro is healing via Kurose's endearments AND we can also see that Shiro is so in love with Kurose as well as dependent on him too much. To me, I think that Kurose isnt in love with Shiro, all he do was repeating the past and try to mend the thing he did wrong. Remember, he attracted to Shiro's mental illness to begin with. So once the story unveils those things, Shiros gonna hurt like a bitch.
And to your question, its more like Shiros scared of getting dirty than dirty someone?! I dont know, thats what i think hahahaha.
Some shady shit is going on...
