Giving 4stars because I fell in love with the show and the cast in the beginning upto ep14. The finale was just terribly off and poorly written for me.
SPOILERS AHEAD:
The illness and death scenes were so unnecessary. They should have left it with the breakup and had Jun return when he was fully healed. I couldn't grasp the idea of him having to be dead for 5 yrs and let everyone mourn for him then make his character come back right at the very last minute of the show. That part made the story turn badly that it completely ruined everything for me.
Nevertheless, I loved the main cast and their chemistry was astounding. All the supporting cast were also amazing.
If it hadn't been for Jun's unnecessary death and 5yr disappearance, i would have given this show a 5star rating.
