They have a similar feel initially.. the storyline is completely different but a lot of things give a similar feeling for instance the fighting, gangs and the older woman who falls for the ML because he protects and cares for her, but i found the couple in 'only side by side with you' cuter than in K2.
I feel like the main characters in both of these dramas have a lot of similarities. Both of the male leads fall hard for he girls. The male leads both have military backgrounds. And the male lead both seem like they are walled off but are really giant teddy bears. The female leads i feel are similar too. They both have great ambition and confidence in the skills they have. The female leads are also both very calm, which i feel are hard to find in cdramas
I definitely feel like if you like one you'd like the other!!
