No, if you read 'If You Hate Me So' the characters are in there but there two completely different storylines. In 'If You Hate Me So' Hyesung and Dojin appear in there but are playing two entirely different characters with an entirely different storyline and plot, if it makes sense.
Hyesung and dojin are from if you hate me so (side couple) but then they got their own story love is an illusion set in an omegaverse
I think Hyesoo and Dojin in If Hate Me so is a non-omegaverse couple. I don't know. Same treatment with each other and maybe worse ╮(￣▽￣)╭
Like an alternative universe.
"Love Is An Illusion" is a spin off of "If You Hate Me So". Theyre written by the same author :>
there's an author's note abt this in "if you hate me so".. the author said that hyeseong and dojin are going to be the main in "love is an illusion" but they are not connected in "if you hate me so"
PS
hyeseong in if you hate me so is 27 years old while in love is an illusion he is 20 years old
meanwhile, dojin in if you hate me so is 32 years old while in if you hate me so he is 25 years old
love is an illusion*
Okay I get confused about the couple in "Love Is an Illusion" because weren't they in "If You Hate Me So"?
