Summary of "The Most Beautiful Gift":

Before filming yet another 'Couple Talk' episode, our beloved couple YunJae found themselves into another fight all due to Jaejoong's jealousy and Yunho's secret phone calls. Refusing to solve this misunderstanding, once the filming was over, Jae locked himself in the dressing room denying anyone to reach him...even Yunho. Hours later, when he had calmed down, Jae made his way to the exit however no one was inside; none of the staff was in there and the doors were all locked. Panicked as he was Jae would have never thought what was about to happen for he was not the only one inside. A strange man had entered and made sure to burn this old building down, ignoring the fact that another man was trapped in there. 
 Hearing from the news that the studio was on fire, Junsu, Micky, Changmin and Yunho made their way to the place in order to find Jae and save him on time. But odds and luck seemed to be against them for Yunho as well got trapped int he same room as Jae. The couple was now convinced that this would be the end...that this was how they'd die. But not all hope was lost. The leader had one last ace hidden in his pocket. Once escaping, they ran towards the car but...someone was there to block their way,..
 

After the incidence with the fire at the studio, Jae was hospitalized as he was suffering really heavy wounds from both the flames and the exhaustion that had taken over him. The young singer had fallen into a comma for several days and once he woke up he only found Junsu, Yoochun and Changmin waiting for him. Yunho was nowhere to be found. Only a letter was left behind; a letter that was delivered to Jae by Micky; a letter written by Yunho that created even more questions in the young man's head. Why had his lover gone away? why was he in such a rush? Why was he not there to wait for him?  And the most important of all; what had happened back at that terrible night? For his memory of that night had left him and whenever he was trying hard to remember his head would hurt him and his heart would reach the edge of breaking.
