For those who are confused, I read the raw of chapter 4, here's a summary (skipping over the parts of the scanlation that weren't confusing):
http://www.mangago.zone/read-manga/23_45_re/uu/23_45_re-chapter-4/6/
Mimori was complaining about the climb, so Iku called him a city boy and asked "come to think of it, where are you from?" Mimori asked if this was an Omiai (marriage interview, because Iku was asking personal questions), and Iku got angry and said he didn't mean it like that, he already stopped liking Mimori.
http://www.mangago.zone/read-manga/23_45_re/uu/23_45_re-chapter-4/8/
Here when Mimori asked "even though you stopped liking me?" Iku reiterated, "wanting someone to live doesn't mean you like them in that way."
http://www.mangago.zone/read-manga/23_45_re/uu/23_45_re-chapter-4/9/
Mimori asked "is it okay to wish for anything with after giving just 100 yen?"
Iku said he wished for Mimori to not fall anymore, and after Mimori said that if you tell someone your wish it won't come true, Iku went back to do it over and told Mimori not to ask him again.
http://www.mangago.zone/read-manga/23_45_re/uu/23_45_re-chapter-4/10/
Mimori wondered if it was okay to keep this kind of distance even though there are still so many things he didn't know about Iku.
http://www.mangago.zone/read-manga/23_45_re/uu/23_45_re-chapter-4/12/
Iku wondering what would have happened if they met more normally, but then said he couldn't help but reminisce about the past that they couldn't return to.
http://www.mangago.zone/read-manga/23_45_re/uu/23_45_re-chapter-4/15/
Mimori stopped Iku from buying tickets, and then said that he didn't want to talk about the past, but the future.
Iku questioned why even though Iku had decided to end it, Mimori was digging up things up again. He said that even though things were going his way, he was tired of saying things that won't come true.
Mimori asked "that's why you're stopping?"
Then Mimori said he thought Iku was rude because he was looking at the ghost and not him, even though he was the one standing right in front of Iku, and before he knew it he had been constantly thinking of Iku.

Mimori: Also, I hated it when you said you would stop liking me, so I'd be happy if you stopped stopping [liking me]
Iku: Even though you said you didn't understand what I told you? [the stories about the ghost] Even though you said that you can't give me anything?

"A living Mimori-san" "Right now, I will love the you who is living"
Sorry, somehow in the middle it turned to straight dialogue translation.
