Both feature past construction accident and both revolve around the architecture industry. ML from Love between Lines and 2ML from Rain or Shine share similar story.
Rain or Shine is a bit heavier and it's based on a real tragedy, while Love between Lines also depicts immersive mystery VR game.

Female leads go into a book, and they both try to make the male lead fall for them while following the script, but they way they go about it is different, which makes this a comedyso they both are rom-coms.

Both female leads were transported back in time through a book that they were both criticising and had to complete quest in order to move to the next round they were both NPC’s in the book that they didn’t like.

Revenge after a terrible traumatic past, SA. Kinda similar love stories because only love was the only one good thing in main lead's adult life

The character's actions in the game/book are quite similar to the tasks, and the fact that there are rewards and punishments at the end is also similar.

Similar storyline, I suspect it's a remake but have never found info on whether or not it was. Truly, if you enjoy Butterfly, the storyline in Like You, Me Too is almost identical. I especially love Xiang Yun Jie & Wang Yu Feng's chemistry that I felt matched well with Xie Hong Xin and Wang Yun Yun's.

Both have transmigration plots where the female lead is drawn inside a book with specific rules that they must abide by in order to survive and return to the real world.

Strange things are happening. A group of people coming together to solve mysteries forming friendships and fighting bad guys.

takes place in the same universe though i'm pretty sure it's wayyyy after the events of TTEOTM. the novel of TATMF mentioned TTEOTM briefly so it's not super connected, but both is center around a demon male lead

Both are related to the occult/supernatural. Both main characters are cursed to see ghosts and fall in love with a romantic partner. Both side couples are also really cute and also get involved with the occult. Both have amazing OSTs and amazing plot with chemistry.
