7 Days Before Valentine (2023)

Even though it has a different story background, Marry My Dead Body has the same story concept as 7 Days Before Valentine. Where the main character wants to return to his old partner. In MMDB: Mao Bang Yu wanted to visit his old boyfirend, with the help of Wu Ming Han, but unfortunately something unexpected happened. Even though they don't focus on that kind of thing, both are supernatural and the main character communicates with astral beings (spirits) who guide or at least provide good experiences for the other main characters.

Both of the series feature a love story between a human and a grim reaper. Also focuses on death too.

The male leads are both being surrounded by spirits. But also their differences make both series unique. "7 Days Before Valentine" surrounds Sunshine who needs to understand that the world doesn't revolve around him rather to understand who we are and what our purpose is, while at the same time knowing others and understanding them as well. In "The Whisperer", the male lead Khun has always been told that he's crazy and only does "bad things". However, he won't seek revenge towards those to have lied to him, rather show them what "crazy" really is.

This series has the same supernatural form, namely an angel who matches humans or at least an angel who helps someone return to their lover. Even though these two series have different plots, the form of the story is almost the same.
