https://www.mangago.zone/read-manga/the_foul/ or https://www.mangago.zone/read-manga/betting_on_you/ ? those are two popular manhwa that has gambling elements
oh wait. i think i know the story you might be referring to. is it this one https://www.mangaupdates(.)com/series/vzlsl23/burst-out (just remove the parenthesis)? iirc, i don't think it's here anymore because the author might've requested for it to be removed. i'm not sure if i'm recalling it correctly tho. that might've been a different one.
yeah.. i was searching for this one, thank you for the others tho atleast i can add something to my want to read
you're wc (●'◡'●)ﾉ
SOMEONE please help me out there’s this bl burst out (not the one that.. pops up first when you search it, it’s about gambling or idk…) i don’t know if it’s uploaded on here, i found it on another websites but it’s either in russian or indonesian. i also don’t know if it has any alter names so if anyone knows something about it being on here i would thank them
