There are so many parallels between the two, both have time traveling depressed suicidal lovers saving each other, the male leads are both dealing with a lot internally but are absolutely obsessed with the love interest and find solace through them, Seon Jae & Yeowoon are green flag golden retriever boyfriends, both are athletes that end up with injuries, the main character is a fan of the male lead and both couples seem to not be able to exist without one another… there is so much more I could go on & on about.
