I remember a story from this one maybe matching your description https://www.mangago.zone/read-manga/bannin/
Not a webtoon + daughter could help narrowing down.
Do you remember anything else? Was it a full volume or only some chapters? Job for any of the character?
Also check some lists like https://www.mangago.zone/home/mangalist/290519/?filter=&page=1 and see if anything seems familiar?
Also the tags https://www.mangago.zone/tag/single+parent/ or https://www.mangago.zone/tag/guys+with+kids/
Jm pretty sure you mean this one

Tysm for replies and your time!
I knew it was a long shot, none of the ones linked are the one.
It only had some chapters but I don't remember more unfortunately!!
(I had a thought the single dad may own/work at a restaurant but that might be mixed up with another one so probably not)
Thank you for your attempts
Could it be this one? https://www.mangago.zone/read-manga/ikumen_after/
This might be a challenge because I don't remember many details!!
It's about a younger guy who meets a single older dad outside somewhere with his.. daughter? , they become friends and the younger guy ends up interested in the dad but the dad is unsure of a relationship, it was short I think. And probably a biiit older, definitely not a webtoon!
Thank you if you attempt to help
