이방인 or Stranger by Seonmyeong. The specific scene you mentioned is Chapter 69. (Also the guy who gives him the cheque isn't the ML if I remember correctly)
TYYY
I'm just genuinely curious, how do you remember this down to the specific chapter?
I have really good memory about not so important stuff (wish it worked with school work) I saw an edit of it like 6 years ago maybe more, maybe less if the manhwa/chapter wasn't made yet and I guess it had such an impact that I just remembered it down to the details.
This BL is known or at least I have seen a lot of edits with is a scene where the mc leans over a table to grab a bill from the MLs hand/fingers
they are inside like a club and there are people around the ML
when Mc Walks in cause he works there (I think he is dept shocker) to pay his bills and then the ML like finds him sexy and said something like "Ill give you this bill if you crawl" and mc crawls on over the table and like used his mouth to grab the bill
This is the only thing ik about this manhwa please help(〜￣△￣)〜
