Fellas if y'all are looking for a blossoming relationship between a bodyguard & a prince in an eastern historical context then look no further.... I've been blessed with the cutest possible wholesome shit right here. First off, Dangeum is Jigyo's (the prince) guard from the shadows but since they're on the run from the palace coz of some "who's next in line for the throne" royal struggle; Dangeum's been given the chance to reveal his identity in front of the prince. Coupling with the fact that Dangeum loves Jigyo with his wholeass heart, this runaway ordeal proves to be Dangeum's lifelong goal as he gets to spend time with the prince. You can see him becoming more bold as their days progress, like nibbling Jigyo's ear and laying on his lap *kokoro explodes*.
Most moments are taken up by these two & the grandfather on occasions, quite predictable since the title's literally about them both. Ya can carefully follow the plot by paying attention to the interspersed scenes regarding to what happened prior to their exile. There'll be two more seasons so expect some major royal battle for the throne, Dangeum's origins & stuffs. But the art's cute so the fights will be the least exciting out of all.
