As many shorter K-BLs, this is a snack for in-between; light, without much substance but well-executed for what it is.

What I liked:
* This movie is a visual delight. The actors are cute, the lighting at night is bright and fits the mood, the sets look comfy.
* The background music confirms the light-heartedness of the story.
* The story does not pretend to be anything but what it is: A light and simple love story.
* The straightforwardness of the younger guy was refreshing, I loved how he made it very clear what he wanted, without pressuring the chef.

What I did not like:
* I wish the plot would focus on either the chef's inner journey from "Is it possible I find another man cute?" to "I want a relationship with him, even if my friend wants it too!" or the love triangle. Doing both means that they couldn't do either enough justice within the time frame they had.
* Why the timeskip at the end? It did not add anything meaningful to the plot or the character development, and it took away from the emotional impact that the couple had their happy ending. Maybe it was supposed to be a set-up for a possible sequel? It would explain why the usually more stoic chef would cry so hard during the hug.
* The realist in me is pointing out that a rooftop restaurant with comfy chairs and sofas is not a sensible thing: If it rains, everything will get wet. And what about winter?

Overall, like some other Korean BL-movies, a nice way to spend an afternoon if you need something where everybody is beautiful and nothing hurts (much) -- but you won't miss anything if you skip this one.
