They are similar in terms of three women who have tight friendship, though Sweet Teeth is a pure Romantic Comedy drama and Thirty-Nine is a tearjerker drama. However, despite the two totally different storyline, if you're interested in seeing jealous worthy sismance between three women, then the two dramas are totally worth watching.

Furthermore, I think Sweet Teeth is focused more on the relationship between the three women and their partners and Thirty-Nine is more focused on a beautiful and touching story about the friendship of the three women.

Both are mini dramas with one of the leads trapped in a day long time loop.
