Are there sex smut scenes?

It's confusing but i think it doesn't, there's a explicit versión but that's with patreon i think (or somewhere else you need to pay), on webtoons is only the normal version, neverthless, there are some explicit scenes here but if i remember correctly, they clarify that's like a AU not canon per se.

I can be wrong tho (with the last part of me saying those scenes are not canon)
