I have to agree with some of the commenters bellow, Tracy was the overall victim of the situation,he had all of them turn their backs on him and now everything is going to be oh so magically fixed even when he is still the only one trying to make things work in all his relationships with the people he was most closest to.
Really I don't like how all three of them knew where he was yet kept ignoring him. They basically were like: " I found my happiness so screw the guy we used to know"
I'm sorry but honestly things could have turned out better, if they were as honest as Tracy.
I did like how the plot was but after all that drama, it's kind of putting me off reading how just one character suffered and is still suffering because of lack of communication and honesty.
I know I'm been a bit mean but honestly I wished they (Alex, Callen and Jess) could be more sympathetic and caring towards him. Callen did have a brief heart to heart with Tracy but even still it did not have as much impact.
But good job author-san your grammar and spacing was great, the story pacing was fine until the time gap. Maybe putting a disclaimer e.g) 1 year latter, at the top would make reading the plot transitions better. Overall I still wish to read the next chapter, mostly to find out if the other three do having some saving grace.
