The usual gangster x normal person trope, definitely leans heavy on all the trope characteristics like the gangster guy being huge and imposing in every social situation ever. They had a little build up before getting together, both of them slowly realizing their feelings and coming to terms with them. For Sanghwa it was all about overcoming his past love and moving on, for Gwon it was about finding friendship for the first time and then that feeling growing into attraction.
The game premise continues throughout, sprinkled in the story, but their relationship is focused on their offline interactions (unlike manhwa such as My Darling Just Signed In.) The guild meetings happen a few times as well, giving a chance for character growth with other friends.
I liked how the friendship with Ryuh Han evolved after the first interactions, and I feel like it was handled better than expected as most manhwa tend to have a more negative outcome for similar situations.
Some parts are cheesy, it's to be expected from a romance that isn't focused heavily on drama and angst. There were funny moments, quite a few scenes that made me chuckle, and I feel like what drama there was was nicely balanced by the humor.
The art is nice, easy on the eyes, characters designs are very easy to tell apart, and the overall style is reliable and doesn't change in appearance throughout the chapters.
As far as maturity rating goes, the characters do have sex but it is censored extremely heavily to the point that you can only really see their faces and a few bits of upper body/legs (no lightsabers). So, not appropriate for most youth, but fine for teens and up probably.
