To me it’s the Jae-ha from the past, continuing his life without doing at graduation day.
And the Yeon-ho from the future died, it leaves the space for the two who are still alive to grow up happily ;;
<SPOILERS!>It would have been nice if the alternative ending was close to the original ending.It feels like a continuation of the original ending and Yeon-Ho was just having a nice dream to me before he really died.
╥﹏╥
