Both romance with a frenemies situation. But in like a palette only Jane thinks Dai hates her even tho Dai likes her. In like a palette I don't think they have a side couple though.
Both bl dramas the actors look very similar but more differences then similarities but I couldn't think of a better recommendation. In melody of secrets the main character has memory loss from a tragic accident, which limits his memories on his past lover, Tankhun. He gets a mail delivery one day with a diary that was once his. Tankhun and him meet up and find a body. Melody of secrets is really interesting so far but I'm not sure how they are going to end it.
Frenemies to lovers and the characters are pretty similar. The starting episodes both line up with the fact that they have some scenes where for example, Jinn falls on J and they get really close, the main difference is that they are in different time lines and dare you to death seems to not have a side couple.
