my first ever lakorn was Hua Jai Sila (2017) and, like you, i had a love-hate relationship with it but i would still recommend it as it became sort of a guilty pleasure to watch it! according to the tags, both hua jai sila and kluen cheewit are revenge dramas.
one way to get recs would be to go through the recommendations list of your fav drama. in this case, you will find dramas that people of mdl have found to be similar in term of genre, plot, etc. to the drama you like.
i've also found these two articles to be really great when searching for your next lakorn to watch, especially if the Slap Kiss aspect of lakorns interests you :
hope this helps a bit!
