Not bad. Since it's a oneshot, there isn't much character depth or character progression. The romance also feels a little slow to start because the two leads essentially start off as good acquaintances / colleagues. The tone feels a little mature in how the characters are written-- no overly blushy characters, no big misunderstandings, just two adults who decide to give a relationship a go. I liked it but probably would have gotten bored if this had been a longer story, so I think the length is just right.
