Riki used to be your best friend but you two have always liked each other.. But there's this murderer that has you as one of his target, but everytime he try to kill you, Ni-ki always get in the way.. saving you but this was in the 2013

Now, 2024, the killer got out of prison and is now still planning to go after you but instead he went to Ni-ki and killed him instead so no one would get away

You were heartbroken after this and of course scared. While crying, you accidentally clicked the watch he gave you and you're suddenly brought back to 2013, you took this as an opportunity to save him and prevent him from dying in the future but you had to make him stay away from you but he was clueless about this and thought you were just avoiding him because you don't like him

One time, you were drunk and was about to fall off the building you were standing on but Ni-ki stopped you from falling and pulled you onto him
