I was thinking the same thing as well! But then teach reached out and looks like about to kiss him, but then knowing his level of knowledge, sleeping with teach might also mean s*x with him, like U know how kids can be gullible and believe something mean different..? Guwon is giving that vibe, ya know what I mean?

That is NOT the definition of grooming.
"Grooming: the practice of preparing or training someone for a particular purpose or activity."
That and brushing, cleaning or such are the ONLY meanings of this word.
Not sure where you got yours from, but it's inaccurate and should not be used that way as it waters down this serious term in this context.
Okay, not sure about the original sentence but I hope we are all aware that "Wanna sleep with me?" could just be him being his naive self literally asking if they could sleep next to each other instead of bonking. XD
Given his personality so far, I am actually expecting that rather than him just randomly saying: Let's fuck.
Would also give way to an awkwardness arc and Guwon figuring out Teach's romantic interest.
