Can someone clarify to me the timeline cuz from what i can remember from the first chap the mc was telling stories, saying how much he hates ml and the other guy. So that means they're older and graduated (?) and means that first chap is the present and its just showing flashbacks (?) if ever they why is he still friends with that fcker!?!! Because in this recent chapters they seem not close anymore and the mc is falling out of love w him so what's what....pls help
