I'm not sure where most people would watch dramas but I found a really good website with tons of dramas that are ad-free. The link to the first ep of Love Is Sweet is right here: https://www3.dramacool.movie/love-is-sweet-2020-episode-1.html

Warning: there are some sexual ads surrounding the vid and there is a lights-off option under the vid that just darkens the whole screen except the vid so that's a tip to ignore them. :)
