i dont know if you've found it but is it this one you're looking for? https://www.mangago.zone/read-manga/saiteina_otoko_no_ude_no_naka/
do you know of any other stories (that are not Webtoons), where one hears the neighbour do the deed and then they like have issues and end up together though.
There was this story I am looking for. The loud neighbour also let his straight couple friends stay over and do it in his place. So once that guy then came to the house of the mc who was hating on him initially for being so loud and like he falls for him.
