Hmm..I think that line coming from "Hotaru". He said "we are going out" referring to him and Asada because the black hair dude asked if Asada the one who gave him the mark.
Just my guess.
yes maybe he is playing the characters from the book with his friend. lets see i'm curious
No, I meant the Hotaru guy the one who said 'we are going out' to the black dude. Not the black dude who said that (￣∇￣") sorry for confusing you with my words.
Btw yes, I also think that the Hotaru guy (can't remember his name as I'm typing this comment) had read the book and has something fishy going on.
Ah, now I get it thanks . then I think his friend is just worried about him or in love with him
but wait did he cheat on his boyfriend
