Do you know Paljae..?

It's a Wuxia story about immortals, monsters, and gods. It's BL, but both characters are really pretty. You can read it on Ridibooks, and it's rated 15+ I believe.. They're so cute and also very sad. Even though it's about monsters, there are many heartwarming stories. I don't know if it's because I like tsundere characters, but even though I don't usually read BL, I'm really enjoying this one so much.. I've passed 100 chapters and I'm watching it with great satisfaction. Reviewers and critics also say it's the origin of 'reverse childhood friend' tropes.
