After crossing each other's path countless of times over past lifetimes, Chanyeol and Baekhyun decided to spend time apart from each other for a long time. Once they reunite, Baekhyun realises then that he can't live without Chanyeol, nor can he die without him. Chanyeol, on the other hand, realises that love, to him, can only come in the form of a certain boy who can live as long as him. 

Sungjin is sick of getting caught in Jae's mess.  Jae wants to forget his ex.  Younghyun regrets being an .  Wonpil knows he's getting somewhere.    (Or Jae is a reckless immortal and Sungjin is his responsible brother who needs to convince Wonpil that immortals do not exist and to kick Younghyun's before he hurt Jae once more.)    Ps: A Wonpil X Sungjin chapter is coming soon.

How long can you wait for your first love? Jaehyun might have waited 600 years just to see him again

"I made a deal with the devil,"   "I sold him my soul so I could get a chance to see you."   "I've watched you live through happiness and sadness..."   "And I've watched you die,"   "With a broken heart..."   "Everytime..."

He’s not a vampire, nor a werewolf. He’s just a simple boy who happens to be immortal.
