Unfortunatley, Kyousuke's memories were also erased during that incident. Remember the boss said he gave him methamphetamine and he went crazy? Well, this girl explained everything just in one panel here: http://www.mangago.zone/read-manga/itou_san_kuraka_sui/mi/mi_chapter-5/35/ Ito-san brought him to the hospital after the incident, but he couldn't approach him for five years (!?) because, well, they lost their memories, but I think, also because Ito-san was still an assassin (although he's a lone wolf now) and he thought it was too dangerous to involve Kyousuke with him. (rly Itou-san? you're the same as ever)
I was confused as well but your comment make me think harder and understand. :)

Oh, yeah I didn't notice that! Ito-san eventually regained his memories, but only on this chapter: http://www.mangago.zone/read-manga/itou_san_kuraka_sui/mi/mi_chapter-6/1/

But here, he still remembers him, after being drugged. or was the side effect a bit postponed? TT^TT

hmm i see, but here he still rmmbrs Ito-san http://www.mangago.zone/read-manga/itou_san_kuraka_sui/mi/mi_chapter-5/25/
and the ch 6 is mislabeled cuz it's an extra for ch 4, so i think ito woke up completely when he killed those two guys raping kyousuke.... waaah... i need to know what happened in those 5 years >!<

Kyousuke remembers everyting up to page 33, then he falls asleep and when he wakes up (in the hospital or something), he forgets everything: http://www.mangago.zone/read-manga/itou_san_kuraka_sui/mi/mi_chapter-5/34/
Oh, you're right! I was wrong, sorry, Ito-san woke up here: http://www.mangago.zone/read-manga/itou_san_kuraka_sui/mi/mi_chapter-5/33/ since he uttered Kyousuke-kun's name the next page. thanks
can someone explain me the ending? did ito-san place kyousuke to the hospital and made him forget him? why doesnt he rmmbr him? TT_TT why can't they be together? my heart (/TДT)/
