chotto confused

I think the memory loss is a side effect of drugs. Ito probably just watch over Kyosuke while waiting for him to remember.

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

Yup I think so too, he is watching over him and I guess Kyosuke started to respond a bit as he took notice of itou san and asked him who is he.

Well, Ito-san never forced his feelings on Kyosuke, so I supposed He will just wait until he remember or fall in love with him again. I trully believe in an happy ending !!

Indeed he fell in love with him once why not twice

oh ok! Thank you! I really hope he remembers Ito-san. Or if not (which is okay since there were tons of bad memories), he falls in love with him again.
