To make this long story short. In this story, Leeteuk died. So Taeyeon was left alone, after months, she met Onew at her office. They're relationship grows until they became lovers. But eversince Taeyeon started to date Onew, she was disturbed by her nightmares caused by Leeteuk. Then as they travel to Busan since they are going to live there, they have been lost and ending up going to a mansion asking for direction. The hunting starts there, Onew was nearly killed by Leeteuk, Taeyeon too. They were able to escape him, and when they were on the road, Leeteuk was in the backseat, he tried Taeyeon to commit suicide but failed because another car almost hit them, but she managed to dodge it on time. Onew asked her to go out to check the other car, but after she went out. Leeteuk appeared and explained Onew everything, he conquered the man's body before Taeyeon could get back. Taeyeon told Onew(Leeteuk) that she didn't see one. Onew(Leeteuk) said they ran away. She called ambulance to get them away there and to cure the man, when the help arrived, Onew(Leeteuk) thinks that he won the battle b'coz he gets Taeyeon's current bf's body. Until now (in my story) Taeyeon lives with Leeteuk at Onew's body. So i hope this summary helps ^^
