Both are short length series that have hilarious medical reasons for the main characters to kiss a lot : )
In First Kisses the FL needs the kiss of the ML to help with her amnesia and in Love Me in 3 Days the ML needs the kiss of the FL to prevent himself from transforming into someone else. Super ridiculous but they're both short, sweet, and cute, so if you need a quick and quirky little filler series, these two should do.

Both dramas feature the hotel business. The female lead is an employee who deals with different guests. There is some drama around the management of the hotel.
