I'm assuming the story has ended, considering it says only 3 episodes.

Overall, the story is subtle with the fluff, it is there but only for short moments. It's a very chill one!
The does seem to be a little hanged? It feels like they could tell more about the two and progress their relationship even more.
Shing really shows he has some sort of thing for Yiu from the start, or it could just be his straight forwardness.

If you are looking for something that is very very light, short length each episode, and very quick, this story is for you!
I don't hate it, but I do desire more of the storyline hahah
