Shim Changmin is voted as the most lovable k-pop maknae in K-POP.  

I seriously think that this is a tough poll.  I don't know the contenders but I could name some tough competition.

Kyuhyun of Super Junior - One of Voldemin's best friends and his partner in spreading terror to their hyungs.  He is also one of the talented vocals in Super Junior.

Seohyun of Girls' Generation - Many groups would want Seohyun as their maknae (most probably Super Junior) because she is not only gracious but she also respects her unnies like she should be.

Minzy of 2ne1 - She is undoubtedly the best dancer of 2ne1 and also one of the best in KPOP.  She's witty and she could make fun of Bom without looking mean.

Seungri of BigBang -Do I have to explain this?  Seungri is awesome to another level.  He makes boasting cool and funny at the same time.  He spills the bombs for his hyungs and he could get away with it.

Yep, there are lots of lovable maknaes in KPOP and you could probably name some but I do agree that Shim Changmin is the most lovable.  I am not saying this because he is my bias.  Shim Changmin is one of the most badass singers of K-POP with his high notes.  He also managed to terrorize his hyungs without him looking evil at all.  It was usually Jaejoong who gets the blame.  What's the most particular maknae trait that Changmin has is that he could actually make his hyungs do as what he wished.
