Me Too Flower-Ep.6 - Restaurant Kiss -the first part is not my favorite, but it does express a lot of the emotional turmoil happening between the leads. The second part of that kiss is one of the best in dramaland. You really feel that these 2 people are completely lost in each other.
Another Oh Hae Young - All of the kisses were great because both the male and female leads were fully engaged in them.
Suspicious Partner- 1st Kiss between the main leads.
The Coffee Prince kisses are iconic, both in execution and emotion. Healer, Another Miss Oh, Lovers, all of the ones in each Reply series, uhhh.........what else is there? I really need to broaden my perspectives here tbh
