ahhh sorry the late reply, I never check my account! If a novel doesn't have the NSFW tag, it doesn't necessarily mean that s*x doesn't occur. In fact, most of these novels indicate that something  happens. But no explicit descriptions, so unless someone is reading word for word over your shoulder, no one should notice a thing and you should be fine! Also sometimes I forget if NSFW happens hehe bc I write some reviews after reading other novels. I will change the rating for "Don't you like me"! So if anyone thinks I should include NSFW or slightly NSFW I will definitely edit it.
