SHINee and perfection: they come hand in hand.
(I'm proving my own point so I decided to come up with this post inclusive of direct links, images, GIFs, videos, news articles and everything as examples. If you decide to take this out, credit back or something).
[I DON'T OWN ANY OF THE PHOTOS/GIFS/ARTICLES/ETC USED HERE. JUST THAT THIS PIMP POST WAS WRITTEN BY ME]

Onew (Lee Jinki) - Compassionate person, caring and extremely responsible leader, filial son, extremely clumsy/precious (because he's really ditzy), experienced performer (done everything from musicals to MC-ing), 'new variety idol' (this bb tries and sometimes fails to get attention, but still adorable) and everything else.
Naturally adorable looks ~, PERFECT SOOTHING WARM VOICE ALL GIRLS WOULD DIE FOR (THIS IS EVIDENT. ALL ARGUMENTS ARE INVALID).
OTPs (most common first) - Ontae, Onkey.

Jonghyun (Kim Jonghyun) - Dedicated, amazing stage presence, adorable (especially when with Key), hilarious (mostly because he's pretty witty. Known in the fandom for his inability to do Math), awkward and attention-seeking (both in good ways!).
Blows you away with his killer gaze, resembles a raptor a lot (everyone in the fandom knows :>), STUNNING AMAZING VOCAL ABILITY AND UNDERRATED VOICE YOU DON'T WANNA MESS WITH.
OTPs (most common first) - Jongkey


Key (Kim Kibum) - Almighty Key, Wonderful guardian, #1 diva in the whole Hallyu wave, amazing umma, indescribable, sweet, sentimental/emotional, awkward but adorable both at once, amazing, looks good doing everything, outstanding (fashion sense), absolute camwhorer (facial expressions are to die for, they're so qt), adorable, always attached to Jonghyun, looks amazing as both a guy and a girl, etc.
Absolutely amazing stage presence, kills girls left and right with his flawless smirk, Perfect bone structure (like a work of art you can't stop staring at), amazing good looks, amazing dancer (almost like that of Taemin, but still Taemin's unparalleled), SHINee's triple threat NOT TO BE TRIFLED WITH (you don't need proof, I'm serious).
OTPs (most common first) - Jongkey, Onkey, Minkey, Taekey.

Minho (Choi Minho) - Hyung whore, qt expressions, comical (sometimes), tends to be pretty whimsical ~, atheletic, amazing stage presence, VERY determined and competitive, gorgeous and manly (LMAO), amazing father figure (sweet also applies), realistic, diligent.
Really good looking (because he's tall), Charm you see everywhere in him, charisma you can't deny (it inundates you), Amazing rapper, improving steadily as a singer, known very well as a total cockblocker (LMAO).
OTPs (most common first) - 2min, Minkey.

Taemin (Lee Taemin) - Amazing dancer, amazing singer (look for them both yourself, you'll be dazzled because flawless boy is flawless), looks adorable doing everything, aegyo bb, adorable magnae, amazing actor, AMAZING STAGE PRESENCE (extremely powerful and totally prection), has a flawless smile, shy and precious, can do everything (from MC-ing to acting), daring, down-to-earth, always focused, hardworking despite his young age, awkward.
Everyone in the fandom is well aware (or more than well aware) than this bb looks EXTREMELY ADORABLE WITH HIS BIG EYES AND DAINTY FEATURES!, he also looks so dainty that it's so easy to mistake him for a girl because basically, he's amazing dressed as both genders, since he's really pretty as girl and really qt as a guy. ~
OTPs (most common first) - 2min, Ontae.
