The Sacred Serpent's Seduction Is super cute and green flag! It’s been a while since I read it but I’m pretty sure dawn of the dragon also wasn’t toxic:)
Definitely The sacred serpent and Melting point
blood bank is super underated. (the manhwa itself is somewhat toxic BUT not the actual relationship, very healthy and cute) w happy ending that truly makes you rethink your life
