Sweet story, great actors, great chemistry.

My main complaint is just it's too short, which means it's a little rushed, development-wise.
The time progression is unclear; it was definitely not love at first sight, so how long has it been since they met and develop feelings? CSW clearly had a gay panic after the almost-kiss, but the drama doesn't show much of his feelings and suddenly, he took the initiative to kiss PJY? It was a little sudden IMO. Not enough build-up to make it squee-worthy.
Other than that, this is absolutely a gorgeous drama. I wish there's more.
