A Slight Smile is Very Charming is the story that Really, Really Miss You could have been. The setting is also similar to Black Belly Boss, Don't Run, while it shares the same universe and author as Come and Eat, Shan Shan but the pacing was better and the characters developed their relationship more and gradually fell for each other.

Taking place in an MMORPG, the female lead is ditched by her in-game husband when she encounters her idol/the top ranked PK and he proposes marriage. Working together and interacting with him and his team, they fall for each other in-game and arrange to meet offline. The MC then realizes that her current in-game husband is also her idol in real life and they begin dating and working together offline as well. Throughout the story they also handle trolls and various antagonists.

The story is actually quite simple, however their interactions were quite charming and you could feel the development between the two characters as they don't just rush into love. The female lead is cute but sensible and holds a strong position in-game, although she appears slightly more introverted offline. While the male lead also has a rather dark sense of humour but unlike Shan Shan, this is mostly aimed towards people aside from the female lead.

I also liked how the characters had a clear distinction between game and reality, with the MC above using her real life appearance to compete within the game, and clashing with people irl just because of their feuds online – something I found quite dignified. They're not, however, above revenge in game.

Their interactions offline was a touch more stifled though – but mostly because they didn't have quests and supporting characters to help their relationship grow through non-conversational means (while the author spent a lot more time on their in-game wedding than their actual one...). The talks they did have were a lot better than RRMY and improved and became more playful over time.
