Maybe bcuz uno does not confess to him duh?? Yeah he's great and all that but don't forget that he's a playboy that has been sleeping with tons of boys and girls. I bet they would not last long if they were together. While for hajun, yes he's such a burden but he love sihyeon and care for him. And yeah, you indeed like a bad boy, aka red flag so I'm not judging
Hajun is not a burden, he is simply a normal civilian like anyone else! Candy and Uno are both secret agents trained to do that kind of job so of course a normal person like Hajun would not be able to do what they do I like Uno as well but Candy's always been into Hajun, he's never been interested in Uno in that way, I mean, he's never been a possible love interest for Candy, so this pair could've never happened anyway...
It should come out a story about Uno and I'm sure he will find someone else who would truly love him, it's better like this...
why do i love bad boys more fuck. agent uno literally everything (smart, royal, can fight) and i think hanje is such a burden lmaooo he cannot compete with candy as much as uno do but still happy for them just too bad it wasn’t uno the ml
